# LanceDB Documentation
|
||||
|
||||
LanceDB docs are deployed to https://lancedb.github.io/lancedb/.
|
||||
|
||||
Docs is built and deployed automatically by [Github Actions](.github/workflows/docs.yml)
|
||||
whenever a commit is pushed to the `main` branch. So it is possible for the docs to show
|
||||
unreleased features.
|
||||
|
||||
## Building the docs
|
||||
|
||||
### Setup
|
||||
1. Install LanceDB. From LanceDB repo root: `pip install -e python`
|
||||
2. Install dependencies. From LanceDB repo root: `pip install -r docs/requirements.txt`
|
||||
3. Make sure you have node and npm setup
|
||||
4. Make sure protobuf and libssl are installed
|
||||
|
||||
### Building node module and create markdown files
|
||||
|
||||
See [Javascript docs README](docs/src/javascript/README.md)
|
||||
|
||||
### Build docs
|
||||
From LanceDB repo root:
|
||||
|
||||
Run: `PYTHONPATH=. mkdocs build -f docs/mkdocs.yml`
|
||||
|
||||
If successful, you should see a `docs/site` directory that you can verify locally.

### Use GPU to build vector index
|
||||
|
||||
Lance Python SDK has experimental GPU support for creating IVF index.
|
||||
Using GPU for index creation requires [PyTorch>2.0](https://pytorch.org/) being installed.
|
||||
|
||||
You can specify the GPU device to train IVF partitions via
|
||||
|
||||
- **accelerator**: Specify to ``cuda`` or ``mps`` (on Apple Silicon) to enable GPU training.

### When is it necessary to create an ANN vector index?

`LanceDB` has manually tuned SIMD code for computing vector distances.
|
||||
In our benchmarks, computing 100K pairs of 1K dimension vectors only take less than 20ms.
|
||||
For small dataset (<100K rows) or the applications which can accept 100ms latency, vector indices are usually not necessary.

|

### How big is my index, and how many memory will it take?
|
||||
|
||||
In LanceDB, all vector indices are disk-based, meaning that when responding to a vector query, only the relevant pages from the index file are loaded from disk and cached in memory. Additionally, each sub-vector is usually encoded into 1 byte PQ code.
|

In LanceDB, all vector indices are **disk-based**, meaning that when responding to a vector query, only the relevant pages from the index file are loaded from disk and cached in memory. Additionally, each sub-vector is usually encoded into 1 byte PQ code.
|
||||
|
||||
For example, with a 1024-dimension dataset, if we choose `num_sub_vectors=64`, each sub-vector has `1024 / 64 = 16` float32 numbers.
|
||||
Product quantization can lead to approximately `16 * sizeof(float32) / 1 = 64` times of space reduction.
|
||||
|
||||
### How to choose `num_partitions` and `num_sub_vectors` for `IVF_PQ` index.
|
||||
### How to choose `num_partitions` and `num_sub_vectors` for `IVF_PQ` index?
|
||||
|
||||
`num_partitions` is used to decide how many partitions the first level `IVF` index uses.
|
||||
Higher number of partitions could lead to more efficient I/O during queries and better accuracy, but it takes much more time to train.
|
||||
On `SIFT-1M` dataset, our benchmark shows that keeping each partition 1K-4K rows lead to a good latency / recall.
|
||||
|
||||
`num_sub_vectors` decides how many Product Quantization code to generate on each vector. Because
|
||||
Product Quantization is a lossy compression of the original vector, the more `num_sub_vectors` usually results to
|
||||
less space distortion, and thus yield better accuracy. However, similarly, more `num_sub_vectors` causes heavier I/O and
|
||||
more PQ computation, thus, higher latency. `dimension / num_sub_vectors` should be aligned with 8 for better SIMD efficiency.
|
||||
`num_sub_vectors` specifies how many Product Quantization (PQ) short codes to generate on each vector. Because
|
||||
PQ is a lossy compression of the original vector, a higher `num_sub_vectors` usually results in
|
||||
less space distortion, and thus yields better accuracy. However, a higher `num_sub_vectors` also causes heavier I/O and
|
||||
more PQ computation, and thus, higher latency. `dimension / num_sub_vectors` should be a multiple of 8 for optimum SIMD efficiency.

To use your own custom embedding function, you need to follow these 2 simple steps.
|
||||
1. Create your embedding function by implementing the `EmbeddingFunction` interface
|
||||
2. Register your embedding function in the global `EmbeddingFunctionRegistry`.
|
||||
|
||||
Let us see how this looks like in action.
|
||||
|
||||

|
||||
|
||||
|
||||
`EmbeddingFunction` & `EmbeddingFunctionRegistry` handle low-level details for serializing schema and model information as metadata. To build a custom embdding function, you don't need to worry about those details and simply focus on setting up the model.
|
||||
|
||||
## `TextEmbeddingFunction` Interface
|
||||
|
||||
There is another optional layer of abstraction provided in form of `TextEmbeddingFunction`. You can use this if your model isn't multi-modal in nature and only operates on text. In such case both source and vector fields will have the same pathway for vectorization, so you simply just need to setup the model and rest is handled by `TextEmbeddingFunction`. You can read more about the class and its attributes in the class reference.
|
||||
|
||||
|
||||
Let's implement `SentenceTransformerEmbeddings` class. All you need to do is implement the `generate_embeddings()` and `ndims` function to handle the input types you expect and register the class in the global `EmbeddingFunctionRegistry`
|
||||
|
||||
```python
|
||||
from lancedb.embeddings import register
|
||||
|
||||
@register("sentence-transformers")
|
||||
class SentenceTransformerEmbeddings(TextEmbeddingFunction):
|
||||
name: str = "all-MiniLM-L6-v2"
|
||||
# set more default instance vars like device, etc.
|
||||
|
||||
def __init__(self, **kwargs):
|
||||
super().__init__(**kwargs)
|
||||
self._ndims = None
|
||||
|
||||
def generate_embeddings(self, texts):
|
||||
return self._embedding_model().encode(list(texts), ...).tolist()
|
||||
|
||||
def ndims(self):
|
||||
if self._ndims is None:
|
||||
self._ndims = len(self.generate_embeddings("foo")[0])
|
||||
return self._ndims
|
||||
|
||||
@cached(cache={})
|
||||
def _embedding_model(self):
|
||||
return sentence_transformers.SentenceTransformer(name)
|
||||
|
||||
```
|
||||
|
||||
This is a stripped down version of our implementation of `SentenceTransformerEmbeddings` that removes certain optimizations and defaul settings.
|
||||
|
||||
Now you can use this embedding function to create your table schema and that's it! you can then ingest data and run queries without manually vectorizing the inputs.
|
||||
|
||||
```python
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
|
||||
registry = EmbeddingFunctionRegistry.get_instance()
|
||||
stransformer = registry.get("sentence-transformers").create()
|
||||
|
||||
class TextModelSchema(LanceModel):
|
||||
vector: Vector(stransformer.ndims) = stransformer.VectorField()
|
||||
text: str = stransformer.SourceField()
|
||||
|
||||
tbl = db.create_table("table", schema=TextModelSchema)
|
||||
|
||||
tbl.add(pd.DataFrame({"text": ["halo", "world"]}))
|
||||
result = tbl.search("world").limit(5)
|
||||
```
|
||||
|
||||
NOTE:
|
||||
|
||||
You can always implement the `EmbeddingFunction` interface directly if you want or need to, `TextEmbeddingFunction` just makes it much simpler and faster for you to do so, by setting up the boiler plat for text-specific use case
|
||||
|
||||
## Multi-modal embedding function example
|
||||
You can also use the `EmbeddingFunction` interface to implement more complex workflows such as multi-modal embedding function support. LanceDB implements `OpenClipEmeddingFunction` class that suppports multi-modal seach. Here's the implementation that you can use as a reference to build your own multi-modal embedding functions.
|
||||
|
||||
```python
|

There are various Embedding functions available out of the box with LanceDB. We're working on supporting other popular embedding APIs.
|
||||
|
||||
## Text Embedding Functions
|
||||
Here are the text embedding functions registered by default.
|
||||
Embedding functions have an inbuilt rate limit handler wrapper for source and query embedding function calls that retry with exponential standoff.
|
||||
Each `EmbeddingFunction` implementation automatically takes `max_retries` as an argument which has the default value of 7.
|
||||
|
||||
### Sentence Transformers
|
||||
Here are the parameters that you can set when registering a `sentence-transformers` object, and their default values:
|
||||
|
||||
| Parameter | Type | Default Value | Description |
|
||||
|---|---|---|---|
|
||||
| `name` | `str` | `"all-MiniLM-L6-v2"` | The name of the model. |
|
||||
| `device` | `str` | `"cpu"` | The device to run the model on. Can be `"cpu"` or `"gpu"`. |
|
||||
| `normalize` | `bool` | `True` | Whether to normalize the input text before feeding it to the model. |
|
||||
|
||||
|
||||
```python
|
||||
db = lancedb.connect("/tmp/db")
|
||||
registry = EmbeddingFunctionRegistry.get_instance()
|
||||
func = registry.get("sentence-transformers").create(device="cpu")
|
||||
|
||||
class Words(LanceModel):
|
||||
text: str = func.SourceField()
|
||||
vector: Vector(func.ndims()) = func.VectorField()
|
||||
|
||||
table = db.create_table("words", schema=Words)
|
||||
table.add(
|
||||
[
|
||||
{"text": "hello world"}
|
||||
{"text": "goodbye world"}
|
||||
]
|
||||
)
|
||||
|
||||
query = "greetings"
|
||||
actual = table.search(query).limit(1).to_pydantic(Words)[0]
|
||||
print(actual.text)
|
||||
```
|
||||
|
||||
### OpenAIEmbeddings
|
||||
LanceDB has OpenAI embeddings function in the registry by default. It is registered as `openai` and here are the parameters that you can customize when creating the instances
|
||||
|
||||
| Parameter | Type | Default Value | Description |
|
||||
|---|---|---|---|
|
||||
| `name` | `str` | `"text-embedding-ada-002"` | The name of the model. |
|
||||
|
||||
|
||||
|
||||
```python
|
||||
db = lancedb.connect("/tmp/db")
|
||||
registry = EmbeddingFunctionRegistry.get_instance()
|
||||
func = registry.get("openai").create()
|
||||
|
||||
class Words(LanceModel):
|
||||
text: str = func.SourceField()
|
||||
vector: Vector(func.ndims()) = func.VectorField()
|
||||
|
||||
table = db.create_table("words", schema=Words)
|
||||
table.add(
|
||||
[
|
||||
{"text": "hello world"}
|
||||
{"text": "goodbye world"}
|
||||
]
|
||||
)
|
||||
|
||||
query = "greetings"
|
||||
actual = table.search(query).limit(1).to_pydantic(Words)[0]
|
||||
print(actual.text)
|
||||
```
|
||||
|
||||
### Instructor Embeddings
|
||||
Instructor is an instruction-finetuned text embedding model that can generate text embeddings tailored to any task (e.g. classification, retrieval, clustering, text evaluation, etc.) and domains (e.g. science, finance, etc.) by simply providing the task instruction, without any finetuning.
|
||||
|
||||
If you want to calculate customized embeddings for specific sentences, you may follow the unified template to write instructions:
|
||||
|
||||
Represent the `domain` `text_type` for `task_objective`:
|
||||
|
||||
* `domain` is optional, and it specifies the domain of the text, e.g. science, finance, medicine, etc.
|
||||
* `text_type` is required, and it specifies the encoding unit, e.g. sentence, document, paragraph, etc.
|
||||
* `task_objective` is optional, and it specifies the objective of embedding, e.g. retrieve a document, classify the sentence, etc.
|
||||
|
||||
More information about the model can be found here - https://github.com/xlang-ai/instructor-embedding
|
||||
|
||||
| Argument | Type | Default | Description |
|
||||
|---|---|---|---|
|
||||
| `name` | `str` | "hkunlp/instructor-base" | The name of the model to use |
|
||||
| `batch_size` | `int` | `32` | The batch size to use when generating embeddings |
|
||||
| `device` | `str` | `"cpu"` | The device to use when generating embeddings |
|
||||
| `show_progress_bar` | `bool` | `True` | Whether to show a progress bar when generating embeddings |
|
||||
| `normalize_embeddings` | `bool` | `True` | Whether to normalize the embeddings |
|
||||
| `quantize` | `bool` | `False` | Whether to quantize the model |
|
||||
| `source_instruction` | `str` | `"represent the docuement for retreival"` | The instruction for the source column |
|
||||
| `query_instruction` | `str` | `"represent the document for retreiving the most similar documents"` | The instruction for the query |
|
||||
|
||||
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
from lancedb.embeddings import get_registry, InstuctorEmbeddingFunction
|
||||
|
||||
instructor = get_registry().get("instructor").create(
|
||||
source_instruction="represent the docuement for retreival",
|
||||
query_instruction="represent the document for retreiving the most similar documents"
|
||||
)
|
||||
|
||||
class Schema(LanceModel):
|
||||
vector: Vector(instructor.ndims()) = instructor.VectorField()
|
||||
text: str = instructor.SourceField()
|
||||
|
||||
db = lancedb.connect("~/.lancedb")
|
||||
tbl = db.create_table("test", schema=Schema, mode="overwrite")
|
||||
|
||||
texts = [{"text": "Capitalism has been dominant in the Western world since the end of feudalism, but most feel[who?] that..."},
|
||||
{"text": "The disparate impact theory is especially controversial under the Fair Housing Act because the Act..."},
|
||||
{"text": "Disparate impact in United States labor law refers to practices in employment, housing, and other areas that.."}]
|
||||
|
||||
tbl.add(texts)
|
||||
```
|
||||
|
||||
## Gemini Embedding Function
|
||||
With Google's Gemini, you can represent text (words, sentences, and blocks of text) in a vectorized form, making it easier to compare and contrast embeddings. For example, two texts that share a similar subject matter or sentiment should have similar embeddings, which can be identified through mathematical comparison techniques such as cosine similarity. For more on how and why you should use embeddings, refer to the Embeddings guide.
|
||||
The Gemini Embedding Model API supports various task types:
|
||||
|
||||
| Task Type | Description |
|
||||
|-------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| "`retrieval_query`" | Specifies the given text is a query in a search/retrieval setting. |
|
||||
| "`retrieval_document`" | Specifies the given text is a document in a search/retrieval setting. Using this task type requires a title but is automatically proided by Embeddings API |
|
||||
| "`semantic_similarity`" | Specifies the given text will be used for Semantic Textual Similarity (STS). |
|
||||
| "`classification`" | Specifies that the embeddings will be used for classification. |
|
||||
| "`clusering`" | Specifies that the embeddings will be used for clustering. |
|
||||
|
||||
|
||||
Usage Example:
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
import pandas as pd
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
from lancedb.embeddings import get_registry
|
||||
|
||||
|
||||
model = get_registry().get("gemini-text").create()
|
||||
|
||||
class TextModel(LanceModel):
|
||||
text: str = model.SourceField()
|
||||
vector: Vector(model.ndims()) = model.VectorField()
|
||||
|
||||
df = pd.DataFrame({"text": ["hello world", "goodbye world"]})
|
||||
db = lancedb.connect("~/.lancedb")
|
||||
tbl = db.create_table("test", schema=TextModel, mode="overwrite")
|
||||
|
||||
tbl.add(df)
|
||||
rs = tbl.search("hello").limit(1).to_pandas()
|
||||
```
|
||||
|
||||
## Multi-modal embedding functions
|
||||
Multi-modal embedding functions allow you to query your table using both images and text.
|
||||
|
||||
### OpenClipEmbeddings
|
||||
We support CLIP model embeddings using the open source alternative, open-clip which supports various customizations. It is registered as `open-clip` and supports the following customizations:
|
||||
|
||||
|
||||
| Parameter | Type | Default Value | Description |
|
||||
|---|---|---|---|
|
||||
| `name` | `str` | `"ViT-B-32"` | The name of the model. |
|
||||
| `pretrained` | `str` | `"laion2b_s34b_b79k"` | The name of the pretrained model to load. |
|
||||
| `device` | `str` | `"cpu"` | The device to run the model on. Can be `"cpu"` or `"gpu"`. |
|
||||
| `batch_size` | `int` | `64` | The number of images to process in a batch. |
|
||||
| `normalize` | `bool` | `True` | Whether to normalize the input images before feeding them to the model. |
|
||||
|
||||
|
||||
This embedding function supports ingesting images as both bytes and urls. You can query them using both test and other images.
|
||||
|
||||
NOTE:
|
||||
LanceDB supports ingesting images directly from accessible links.
|
||||
|
||||
|
||||
```python
|
||||
|
||||
db = lancedb.connect(tmp_path)
|
||||
registry = EmbeddingFunctionRegistry.get_instance()
|
||||
func = registry.get("open-clip").create()
|
||||
|
||||
class Images(LanceModel):
|
||||
label: str
|
||||
image_uri: str = func.SourceField() # image uri as the source
|
||||
image_bytes: bytes = func.SourceField() # image bytes as the source
|
||||
vector: Vector(func.ndims()) = func.VectorField() # vector column
|
||||
vec_from_bytes: Vector(func.ndims()) = func.VectorField() # Another vector column
|
||||
|
||||
table = db.create_table("images", schema=Images)
|
||||
labels = ["cat", "cat", "dog", "dog", "horse", "horse"]
|
||||
uris = [
|
||||
"http://farm1.staticflickr.com/53/167798175_7c7845bbbd_z.jpg",
|
||||
"http://farm1.staticflickr.com/134/332220238_da527d8140_z.jpg",
|
||||
"http://farm9.staticflickr.com/8387/8602747737_2e5c2a45d4_z.jpg",
|
||||
"http://farm5.staticflickr.com/4092/5017326486_1f46057f5f_z.jpg",
|
||||
"http://farm9.staticflickr.com/8216/8434969557_d37882c42d_z.jpg",
|
||||
"http://farm6.staticflickr.com/5142/5835678453_4f3a4edb45_z.jpg",
|
||||
]
|
||||
# get each uri as bytes
|
||||
image_bytes = [requests.get(uri).content for uri in uris]
|
||||
table.add(
|
||||
[{"label": labels, "image_uri": uris, "image_bytes": image_bytes}]
|
||||
)
|
||||
```
|
||||
Now we can search using text from both the default vector column and the custom vector column
|
||||
```python
|
||||
|
||||
# text search

|
||||
)
|
||||
print(frombytes.label)
|
||||
|
||||
```
|
||||
|
||||
Because we're using a multi-modal embedding function, we can also search using images
|
||||
|
||||
```python
|

# image search

query_image_uri = "http://farm1.staticflickr.com/200/467715466_ed4a31801f_z.jpg"

query_image = Image.open(io.BytesIO(image_bytes))
|

actual = table.search(query_image).limit(1).to_pydantic(Images)[0]
|

Representing multi-modal data as vector embeddings is becoming a standard practice. Embedding functions themselves can be thought of as a part of the processing pipeline that each request(input) has to be passed through. After initial setup these components are not expected to change for a particular project.
|
||||
|
||||
Our new embedding functions API allow you simply set it up once and the table remembers it, effectively making the **embedding functions disappear in the background** so you don't have to worry about modelling and can simply focus on the DB aspects of VectorDB.
|
||||
|
||||
You can simply follow these steps and forget about the details of your embedding functions as long as you don't intend to change it.
|
||||
|
||||
### Step 1 - Define the embedding function
|
||||
We have some pre-defined embedding functions in the global registry with more coming soon. Here's let's an implementation of CLIP as example.
|
||||
```
|
||||
from lancedb.embeddings import EmbeddingFunctionRegistry
|
||||
|
||||
registry = EmbeddingFunctionRegistry.get_instance()
|
||||
clip = registry.get("open-clip").create()
|
||||
|
||||
```
|
||||
You can also define your own embedding function by implementing the `EmbeddingFunction` abstract base interface. It subclasses PyDantic Model which can be utilized to write complex schemas simply as we'll see next!
|
||||
|
||||
### Step 2 - Define the Data Model or Schema
|
||||
Our embedding function from the previous section abstracts away all the details about the models and dimensions required to define the schema. You can simply set a field as **source** or **vector** column. Here's how
|
||||
|
||||
```python
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
|
||||
class Pets(LanceModel):
|
||||
vector: Vector(clip.ndims) = clip.VectorField()
|
||||
image_uri: str = clip.SourceField()
|
||||
|
||||
```
|
||||
`VectorField` tells LanceDB to use the clip embedding function to generate query embeddings for `vector` column & `SourceField` tells that when adding data, automatically use the embedding function to encode `image_uri`.
|
||||
|
||||
|
||||
### Step 3 - Create LanceDB Table
|
||||
Now that we have chosen/defined our embedding function and the schema, we can create the table
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
|
||||
db = lancedb.connect("~/lancedb")
|
||||
table = db.create_table("pets", schema=Pets)
|
||||
```
|
||||
|
||||
That's it! We have ingested all the information needed to embed source and query inputs. We can now forget about the model and dimension details and start to build our VectorDB.
|
||||
|
||||
### Step 4 - Ingest lots of data and run vector search!
|
||||
Now you can just add the data and it'll be vectorized automatically
|
||||
|
||||
```python
|
||||
table.add([{"image_uri": u} for u in uris])
|
||||
```
|
||||
|
||||
Our OpenCLIP query embedding function support querying via both text and images.
|
||||
|
||||
```python
|
||||
result = table.search("dog")
|
||||
```
|
||||
|
||||
Let's query an image
|
||||
|
||||
```python
|
||||
from pathlib import Path
|
||||
|
||||
p = Path("path/to/images/samoyed_100.jpg")
|
||||
query_image = Image.open(p)
|
||||
table.search(query_image)
|
||||
```
|
||||
|
||||
### Rate limit Handling
|
||||
`EmbeddingFunction` class wraps the calls for source and query embedding generation inside a rate limit handler that retries the requests with exponential backoff after successive failures. By default the maximum retires is set to 7. You can tune it by setting it to a different number or disable it by setting it to 0. Example:
|
||||
|
||||
```python
|
||||
clip = registry.get("open-clip").create() # Defaults to 7 max retries
|
||||
clip = registry.get("open-clip").create(max_retries=10) # Increase max retries to 10
|
||||
clip = registry.get("open-clip").create(max_retries=0) # Retries disabled
|
||||
```
|
||||
|
||||
NOTE:
|
||||
Embedding functions can also fail due to other errors that have nothing to do with rate limits. This is why the errors are also logged.
|
||||
|
||||
### A little fun with PyDantic
|
||||
LanceDB is integrated with PyDantic. In fact, we've used the integration in the above example to define the schema. It is also being used behind the scene by the embedding function API to ingest useful information as table metadata.
|
||||
You can also use it for adding utility operations in the schema. For example, in our multi-modal example, you can search images using text or another image. Let's define a utility function to plot the image.
|
||||
|
||||
```python
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
|
||||
class Pets(LanceModel):
|
||||
vector: Vector(clip.ndims) = clip.VectorField()
|
||||
image_uri: str = clip.SourceField()
|
||||
|
||||
@property
|
||||
def image(self):
|
||||
return Image.open(self.image_uri)
|
||||
```
|
||||
|
||||
Now, you can covert your search results to PyDantic model and use its property.
|
||||
|
||||
```python
|
||||
rs = table.search(query_image).limit(3).to_pydantic(Pets)
|
||||
rs[2].image
|
||||
```
|
||||
|
||||

|
||||

||||

Embeddings are high dimensional floating-point vector representations of your data or query. Anything can be embedded using some embedding model or function. Position of embedding in a high dimensional vector space has semantic significance to a degree that depends on the type of modal and training. These embeddings when projected in a 2-D space generally group similar entities close-by forming groups.

# How to Load Image Embeddings into LanceDB
|
||||
|
||||
With the rise of Large Multimodal Models (LMMs) such as [GPT-4 Vision](https://blog.roboflow.com/gpt-4-vision/), the need for storing image embeddings is growing. The most effective way to store text and image embeddings is in a vector database such as LanceDB. Vector databases are a special kind of data store that enables efficient search over stored embeddings.
|
||||
|
||||
[CLIP](https://blog.roboflow.com/openai-clip/), a multimodal model developed by OpenAI, is commonly used to calculate image embeddings. These embeddings can then be used with a vector database to build a semantic search engine that you can query using images or text. For example, you could use LanceDB and CLIP embeddings to build a search engine for a database of folders.
|
||||
|
||||
In this guide, we are going to show you how to use Roboflow Inference to load image embeddings into LanceDB. Without further ado, let’s get started!
|
||||
|
||||
## Step #1: Install Roboflow Inference
|
||||
|
||||
[Roboflow Inference](https://inference.roboflow.com) enables you to run state-of-the-art computer vision models with minimal configuration. Inference supports a range of models, from fine-tuned object detection, classification, and segmentation models to foundation models like CLIP. We will use Inference to calculate CLIP image embeddings.
|
||||
|
||||
Inference provides a HTTP API through which you can run vision models.
|
||||
|
||||
Inference powers the Roboflow hosted API, and is available as an open source utility. In this guide, we are going to run Inference locally, which enables you to calculate CLIP embeddings on your own hardware. We will also show you how to use the hosted Roboflow CLIP API, which is ideal if you need to scale and do not want to manage a system for calculating embeddings.
|
||||
|
||||
To get started, first install the Inference CLI:
|
||||
|
||||
```
|
||||
pip install inference-cli
|
||||
```
|
||||
|
||||
Next, install Docker. Refer to the official Docker installation instructions for your operating system to get Docker set up. Once Docker is ready, you can start Inference using the following command:
|
||||
|
||||
```
|
||||
inference server start
|
||||
```
|
||||
|
||||
An Inference server will start running at ‘http://localhost:9001’.
|
||||
|
||||
## Step #2: Set Up a LanceDB Vector Database
|
||||
|
||||
Now that we have Inference running, we can set up a LanceDB vector database. You can run LanceDB in JavaScript and Python. For this guide, we will use the Python API. But, you can take the HTTP requests we make below and change them to JavaScript if required.
|
||||
|
||||
For this guide, we are going to search the [COCO 128 dataset](https://universe.roboflow.com/team-roboflow/coco-128), which contains a wide range of objects. The variability in objects present in this dataset makes it a good dataset to demonstrate the capabilities of vector search. If you want to use this dataset, you can download [COCO 128 from Roboflow Universe](https://universe.roboflow.com/team-roboflow/coco-128). With that said, you can search whatever folder of images you want.
|
||||
|
||||
Once you have a dataset ready, install LanceDB with the following command:
|
||||
|
||||
```
|
||||
pip install lancedb
|
||||
```
|
||||
|
||||
We also need to install a specific commit of `tantivy`, a dependency of the LanceDB full text search engine we will use later in this guide:
|
||||
|
||||
```
|
||||
pip install tantivy@git+https://github.com/quickwit-oss/tantivy-py#164adc87e1a033117001cf70e38c82a53014d985
|
||||
```
|
||||
|
||||
Create a new Python file and add the following code:
|
||||
|
||||
```python
|
||||
import cv2
|
||||
import supervision as sv
|
||||
import requests
|
||||
|
||||
import lancedb
|
||||
|
||||
db = lancedb.connect("./embeddings")
|
||||
|
||||
IMAGE_DIR = "images/"
|
||||
API_KEY = os.environ.get("ROBOFLOW_API_KEY")
|
||||
SERVER_URL = "http://localhost:9001"
|
||||
|
||||
results = []
|
||||
|
||||
for i, image in enumerate(os.listdir(IMAGE_DIR)):
|
||||
infer_clip_payload = {
|
||||
#Images can be provided as urls or as base64 encoded strings
|
||||
"image": {
|
||||
"type": "base64",
|
||||
"value": base64.b64encode(open(IMAGE_DIR + image, "rb").read()).decode("utf-8"),
|
||||
},
|
||||
}
|
||||
|
||||
res = requests.post(
|
||||
f"{SERVER_URL}/clip/embed_image?api_key={API_KEY}",
|
||||
json=infer_clip_payload,
|
||||
)
|
||||
|
||||
embeddings = res.json()['embeddings']
|
||||
|
||||
print("Calculated embedding for image: ", image)
|
||||
|
||||
image = {"vector": embeddings[0], "name": os.path.join(IMAGE_DIR, image)}
|
||||
|
||||
results.append(image)
|
||||
|
||||
tbl = db.create_table("images", data=results)
|
||||
|
||||
tbl.create_fts_index("name")
|
||||
```
|
||||
|
||||
To use the code above, you will need a Roboflow API key. [Learn how to retrieve a Roboflow API key](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key). Run the following command to set up your API key in your environment:
|
||||
|
||||
```
|
||||
export ROBOFLOW_API_KEY=""
|
||||
```
|
||||
|
||||
Replace the `IMAGE_DIR` value with the folder in which you are storing the images for which you want to calculate embeddings. If you want to use the Roboflow CLIP API to calculate embeddings, replace the `SERVER_URL` value with `https://infer.roboflow.com`.
|
||||
|
||||
Run the script above to create a new LanceDB database. This database will be stored on your local machine. The database will be called `embeddings` and the table will be called `images`.
|
||||
|
||||
The script above calculates all embeddings for a folder then creates a new table. To add additional images, use the following code:
|
||||
|
||||
```python
|
||||
def make_batches():
|
||||
for i in range(5):
|
||||
yield [
|
||||
{"vector": [3.1, 4.1], "name": "image1.png"},
|
||||
{"vector": [5.9, 26.5], "name": "image2.png"}
|
||||
]
|
||||
|
||||
tbl = db.open_table("images")
|
||||
tbl.add(make_batches())
|
||||
```
|
||||
|
||||
Replacing the `make_batches()` function with code to load embeddings for images.
|
||||
|
||||
## Step #3: Run a Search Query
|
||||
|
||||
We are now ready to run a search query. To run a search query, we need a text embedding that represents a text query. We can use this embedding to search our LanceDB database for an entry.
|
||||
|
||||
Let’s calculate a text embedding for the query “cat”, then run a search query:
|
||||
|
||||
```python
|
||||
infer_clip_payload = {
|
||||
"text": "cat",
|
||||
}
|
||||
|
||||
res = requests.post(
|
||||
f"{SERVER_URL}/clip/embed_text?api_key={API_KEY}",
|
||||
json=infer_clip_payload,
|
||||
)
|
||||
|
||||
embeddings = res.json()['embeddings']
|
||||
|
||||
df = tbl.search(embeddings[0]).limit(3).to_list()
|
||||
|
||||
print("Results:")
|
||||
|
||||
for i in df:
|
||||
print(i["name"])
|
||||
```
|
||||
|
||||
This code will search for the three images most closely related to the prompt “cat”. The names of the most similar three images will be printed to the console. Here are the three top results:
|
||||
|
||||
```
|
||||
dataset/images/train/000000000650_jpg.rf.1b74ba165c5a3513a3211d4a80b69e1c.jpg
|
||||
dataset/images/train/000000000138_jpg.rf.af439ef1c55dd8a4e4b142d186b9c957.jpg
|
||||
dataset/images/train/000000000165_jpg.rf.eae14d5509bf0c9ceccddbb53a5f0c66.jpg
|
||||
```
|
||||
|
||||
Let’s open the top image:
|
||||
|
||||

|
||||
|
||||
The top image was a cat. Our search was successful.
|
||||
|
||||
## Conclusion
|
||||
|
||||
LanceDB is a vector database that you can use to store and efficiently search your image embeddings. You can use Roboflow Inference, a scalable computer vision inference server, to calculate CLIP embeddings that you can store in LanceDB.
|
||||
|
||||
You can use Inference and LanceDB together to build a range of applications with image embeddings, from a media search engine to a retrieval-augmented generation pipeline for use with LMMs.

# LanceDB Chatbot - Vercel Next.js Template
|
||||
Use an AI chatbot with website context retrieved from a vector store like LanceDB. LanceDB is lightweight and can be embedded directly into Next.js, with data stored on-prem.
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## Development
|
||||
|
||||
First, rename `.env.example` to `.env.local`, and fill out `OPENAI_API_KEY` with your OpenAI API key. You can get one [here](https://openai.com/blog/openai-api).
|
||||
|
||||
Run the development server:
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
# or
|
||||
yarn dev
|
||||
# or
|
||||
pnpm dev
|
||||
```
|
||||
|
||||
Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
|
||||
|
||||
This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
|
||||
|
||||
## Learn More
|
||||
|
||||
To learn more about LanceDB or Next.js, take a look at the following resources:
|
||||
|
||||
- [LanceDB Documentation](https://lancedb.github.io/lancedb/) - learn about LanceDB, the developer-friendly serverless vector database.
|
||||
- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
|
||||
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.

||||
|
||||
## LanceDB on Next.js and Vercel
|
||||
|
||||
FYI: these configurations have been pre-implemented in this template.
|
||||
|
||||
Since LanceDB contains a prebuilt Node binary, you must configure `next.config.js` to exclude it from webpack. This is required for both using Next.js and deploying on Vercel.
|
||||
```js
|
||||
/** @type {import('next').NextConfig} */
|
||||
module.exports = ({
|
||||
webpack(config) {
|
||||
config.externals.push({ vectordb: 'vectordb' })
|
||||
return config;
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
To deploy on Vercel, we need to make sure that the NodeJS runtime static file analysis for Vercel can find the binary, since LanceDB uses dynamic imports by default. We can do this by modifying `package.json` in the `scripts` section.
|
||||
```json
|
||||
{
|
||||
...
|
||||
"scripts": {
|
||||
...
|
||||
"vercel-build": "sed -i 's/nativeLib = require(`@lancedb\\/vectordb-\\${currentTarget()}`);/nativeLib = require(`@lancedb\\/vectordb-linux-x64-gnu`);/' node_modules/vectordb/native.js && next build",

|

## Filtering
|
||||
|
||||
Currently the LanceDB full text search feature supports *post-filtering*, meaning filters are
|
||||
applied on top of the full text search results. This can be invoked via the familiar
|
||||
`where` syntax:
|
||||
|
||||
```python
|

table.search("puppy").limit(10).where("meta='foo'").to_list()
|

```
|
||||
|
||||
## Syntax
|
||||
|
||||
For full-text search you can perform either a phrase query like "the old man and the sea",
|
||||
or a structured search query like "(Old AND Man) AND Sea".
|
||||
Double quotes are used to disambiguate.
|
||||
|
||||
For example:
|
||||
|
||||
If you intended "they could have been dogs OR cats" as a phrase query, this actually
|
||||
raises a syntax error since `OR` is a recognized operator. If you make `or` lower case,
|
||||
this avoids the syntax error. However, it is cumbersome to have to remember what will
|
||||
conflict with the query syntax. Instead, if you search using
|
||||
`table.search('"they could have been dogs OR cats"')`, then the syntax checker avoids
|
||||
checking inside the quotes.
|
||||
|
||||
|
||||
## Configurations
|
||||
|
||||
By default, LanceDB configures a 1GB heap size limit for creating the index. You can
|
||||
reduce this if running on a smaller node, or increase this for faster performance while
|
||||
indexing a larger corpus.
|
||||
|
||||
```python
|
||||
# configure a 512MB heap size

||||
heap = 1024 * 1024 * 512

A Table is a collection of Records in a LanceDB Database. Tables in Lance have a schema that defines the columns and their types. These schemas can include nested columns and can evolve over time.
|
||||
|
||||
This guide will show how to create tables, insert data into them, and update the data. You can follow along on colab!
|
||||
|
||||
## Creating a LanceDB Table
|
||||
|
||||
=== "Python"
|
||||
### LanceDB Connection
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
db = lancedb.connect("./.lancedb")
|
||||
```
|
||||
|
||||
LanceDB allows ingesting data from various sources - `dict`, `list[dict]`, `pd.DataFrame`, `pa.Table` or a `Iterator[pa.RecordBatch]`. Let's take a look at some of the these.
|
||||
|
||||
### From list of tuples or dictionaries
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
|
||||
db = lancedb.connect("./.lancedb")
|
||||
|
||||
data = [{"vector": [1.1, 1.2], "lat": 45.5, "long": -122.7},
|
||||
{"vector": [0.2, 1.8], "lat": 40.1, "long": -74.1}]
|
||||
|
||||
db.create_table("my_table", data)
|
||||
|
||||
db["my_table"].head()
|
||||
```
|
||||
|
||||
!!! info "Note"
|
||||
If the table already exists, LanceDB will raise an error by default.
|
||||
|
||||
`create_table` supports an optional `exist_ok` parameter. When set to True
|
||||
and the table exists, then it simply opens the existing table. The data you
|
||||
passed in will NOT be appended to the table in that case.
|
||||
|
||||
```python
|
||||
db.create_table("name", data, exist_ok=True)
|
||||
```
|
||||
|
||||
Sometimes you want to make sure that you start fresh. If you want to
|
||||
overwrite the table, you can pass in mode="overwrite" to the createTable function.
|
||||
|
||||
```python
|
||||
db.create_table("name", data, mode="overwrite")
|
||||
```
|
||||
|
||||
### From pandas DataFrame
|
||||
|
||||
```python
|
||||
import pandas as pd
|
||||
|
||||
data = pd.DataFrame({
|
||||
"vector": [[1.1, 1.2, 1.3, 1.4], [0.2, 1.8, 0.4, 3.6]],
|
||||
"lat": [45.5, 40.1],
|
||||
"long": [-122.7, -74.1]
|
||||
})
|
||||
|
||||
db.create_table("table2", data)
|
||||
|
||||
db["table2"].head()
|
||||
```
|
||||
!!! info "Note"
|
||||
Data is converted to Arrow before being written to disk. For maximum control over how data is saved, either provide the PyArrow schema to convert to or else provide a PyArrow Table directly.
|
||||
|
||||
```python
|
||||
custom_schema = pa.schema([
|
||||
pa.field("vector", pa.list_(pa.float32(), 4)),
|
||||
pa.field("lat", pa.float32()),
|
||||
pa.field("long", pa.float32())
|
||||
])
|
||||
|
||||
table = db.create_table("table3", data, schema=custom_schema)
|
||||
```
|
||||
|
||||
### From PyArrow Tables
|
||||
You can also create LanceDB tables directly from pyarrow tables
|
||||
|
||||
```python
|
||||
table = pa.Table.from_arrays(
|
||||
[
|
||||
pa.array([[3.1, 4.1, 5.1, 6.1], [5.9, 26.5, 4.7, 32.8]],
|
||||
pa.list_(pa.float32(), 4)),
|
||||
pa.array(["foo", "bar"]),
|
||||
pa.array([10.0, 20.0]),
|
||||
],
|
||||
["vector", "item", "price"],
|
||||
)
|
||||
|
||||
db = lancedb.connect("db")
|
||||
|
||||
tbl = db.create_table("test1", table)
|
||||
```
|
||||
|
||||
### From Pydantic Models
|
||||
When you create an empty table without data, you must specify the table schema.
|
||||
LanceDB supports creating tables by specifying a pyarrow schema or a specialized
|
||||
pydantic model called `LanceModel`.
|
||||
|
||||
For example, the following Content model specifies a table with 5 columns:
|
||||
movie_id, vector, genres, title, and imdb_id. When you create a table, you can
|
||||
pass the class as the value of the `schema` parameter to `create_table`.
|
||||
The `vector` column is a `Vector` type, which is a specialized pydantic type that
|
||||
can be configured with the vector dimensions. It is also important to note that
|
||||
LanceDB only understands subclasses of `lancedb.pydantic.LanceModel`
|
||||
(which itself derives from `pydantic.BaseModel`).
|
||||
|
||||
```python
|
||||
from lancedb.pydantic import Vector, LanceModel
|
||||
|
||||
class Content(LanceModel):
|
||||
movie_id: int
|
||||
vector: Vector(128)
|
||||
genres: str
|
||||
title: str
|
||||
imdb_id: int
|
||||
|
||||
@property
|
||||
def imdb_url(self) -> str:
|
||||
return f"https://www.imdb.com/title/tt{self.imdb_id}"
|
||||
|
||||
import pyarrow as pa
|
||||
db = lancedb.connect("~/.lancedb")
|
||||
table_name = "movielens_small"
|
||||
table = db.create_table(table_name, schema=Content)
|
||||
```
|
||||
|
||||
#### Nested schemas
|
||||
|
||||
Sometimes your data model may contain nested objects.
|
||||
For example, you may want to store the document string
|
||||
and the document soure name as a nested Document object:
|
||||
|
||||
```python
|
||||
class Document(BaseModel):
|
||||
content: str
|
||||
source: str
|
||||
```
|
||||
|
||||
This can be used as the type of a LanceDB table column:
|
||||
|
||||
```python
|
||||
class NestedSchema(LanceModel):
|
||||
id: str
|
||||
vector: Vector(1536)
|
||||
document: Document
|
||||
|
||||
tbl = db.create_table("nested_table", schema=NestedSchema, mode="overwrite")
|
||||
```
|
||||
|
||||
This creates a struct column called "document" that has two subfields
|
||||
called "content" and "source":
|
||||
|
||||
```
|
||||
In [28]: tbl.schema
|
||||
Out[28]:
|
||||
id: string not null
|
||||
vector: fixed_size_list<item: float>[1536] not null
|
||||
child 0, item: float
|
||||
document: struct<content: string not null, source: string not null> not null
|
||||
child 0, content: string not null
|
||||
child 1, source: string not null
|
||||
```
|
||||
|
||||
#### Validators
|
||||
|
||||
Note that neither pydantic nor pyarrow automatically validates that input data
|
||||
is of the *correct* timezone, but this is easy to add as a custom field validator:
|
||||
|
||||
```python
|
||||
from datetime import datetime
|
||||
from zoneinfo import ZoneInfo
|
||||
|
||||
from lancedb.pydantic import LanceModel
|
||||
from pydantic import Field, field_validator, ValidationError, ValidationInfo
|
||||
|
||||
tzname = "America/New_York"
|
||||
tz = ZoneInfo(tzname)
|
||||
|
||||
class TestModel(LanceModel):
|
||||
dt_with_tz: datetime = Field(json_schema_extra={"tz": tzname})
|
||||
|
||||
@field_validator('dt_with_tz')
|
||||
@classmethod
|
||||
def tz_must_match(cls, dt: datetime) -> datetime:
|
||||
assert dt.tzinfo == tz
|
||||
return dt
|
||||
|
||||
ok = TestModel(dt_with_tz=datetime.now(tz))
|
||||
|
||||
try:
|
||||
TestModel(dt_with_tz=datetime.now(ZoneInfo("Asia/Shanghai")))
|
||||
assert 0 == 1, "this should raise ValidationError"
|
||||
except ValidationError:
|
||||
print("A ValidationError was raised.")
|
||||
pass
|
||||
```
|
||||
|
||||
When you run this code it should print "A ValidationError was raised."
|
||||
|
||||
#### Pydantic custom types
|
||||
|
||||
LanceDB does NOT yet support converting pydantic custom types. If this is something you need,
|
||||
please file a feature request on the [LanceDB Github repo](https://github.com/lancedb/lancedb/issues/new).
|
||||
|
||||
### Using Iterators / Writing Large Datasets
|
||||
|
||||
It is recommended to use itertators to add large datasets in batches when creating your table in one go. This does not create multiple versions of your dataset unlike manually adding batches using `table.add()`
|
||||
|
||||
LanceDB additionally supports pyarrow's `RecordBatch` Iterators or other generators producing supported data types.
|
||||
|
||||
Here's an example using using `RecordBatch` iterator for creating tables.
|
||||
|
||||
```python
|
||||
import pyarrow as pa
|
||||
|
||||
def make_batches():
|
||||
for i in range(5):
|
||||
yield pa.RecordBatch.from_arrays(
|
||||
[
|
||||
pa.array([[3.1, 4.1, 5.1, 6.1], [5.9, 26.5, 4.7, 32.8]],
|
||||
pa.list_(pa.float32(), 4)),
|
||||
pa.array(["foo", "bar"]),
|
||||
pa.array([10.0, 20.0]),
|
||||
],
|
||||
["vector", "item", "price"],
|
||||
)
|
||||
|
||||
schema = pa.schema([
|
||||
pa.field("vector", pa.list_(pa.float32(), 4)),
|
||||
pa.field("item", pa.utf8()),
|
||||
pa.field("price", pa.float32()),
|
||||
])
|
||||
|
||||
db.create_table("table4", make_batches(), schema=schema)
|
||||
```
|
||||
|
||||
You can also use iterators of other types like Pandas dataframe or Pylists directly in the above example.
|
||||
|
||||
## Creating Empty Table
|
||||
You can create empty tables in python. Initialize it with schema and later ingest data into it.
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
import pyarrow as pa
|
||||
|
||||
schema = pa.schema(
|
||||
[
|
||||
pa.field("vector", pa.list_(pa.float32(), 2)),
|
||||
pa.field("item", pa.string()),
|
||||
pa.field("price", pa.float32()),
|
||||
])
|
||||
tbl = db.create_table("table5", schema=schema)
|
||||
data = [
|
||||
{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
|
||||
{"vector": [5.9, 26.5], "item": "bar", "price": 20.0},
|
||||
]
|
||||
tbl.add(data=data)
|
||||
```
|
||||
|
||||
You can also use Pydantic to specify the schema
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
from lancedb.pydantic import LanceModel, vector
|
||||
|
||||
class Model(LanceModel):
|
||||
vector: Vector(2)
|
||||
|
||||
tbl = db.create_table("table5", schema=Model.to_arrow_schema())
|
||||
```
|
||||
|
||||
=== "Javascript/Typescript"
|
||||
|
||||
### VectorDB Connection
|
||||
|
||||
```javascript
|
||||
const lancedb = require("vectordb");
|
||||
|
||||
const uri = "data/sample-lancedb";
|
||||
const db = await lancedb.connect(uri);
|
||||
```
|
||||
|
||||
### Creating a Table
|
||||
|
||||
You can create a LanceDB table in javascript using an array of records.
|
||||
|
||||
```javascript
|
||||
data
|
||||
const tb = await db.createTable("my_table",
|
||||
[{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
|
||||
{"vector": [5.9, 26.5], "item": "bar", "price": 20.0}])
|
||||
```
|
||||
|
||||
!!! info "Note"
|
||||
If the table already exists, LanceDB will raise an error by default. If you want to overwrite the table, you need to specify the `WriteMode` in the createTable function.
|
||||
|
||||
```javascript
|
||||
const table = await con.createTable(tableName, data, { writeMode: WriteMode.Overwrite })
|
||||
```
|
||||
|
||||
## Open existing tables
|
||||
|
||||
If you forget the name of your table, you can always get a listing of all table names:
|
||||
|
||||
|
||||
=== "Python"
|
||||
### Get a list of existing Tables
|
||||
|
||||
```python
|
||||
print(db.table_names())
|
||||
```
|
||||
=== "Javascript/Typescript"
|
||||
|
||||
```javascript
|
||||
console.log(await db.tableNames());
|
||||
```
|
||||
|
||||
Then, you can open any existing tables
|
||||
|
||||
=== "Python"
|
||||
|
||||
```python
|
||||
tbl = db.open_table("my_table")
|
||||
```
|
||||
=== "Javascript/Typescript"
|
||||
|
||||
```javascript
|
||||
const tbl = await db.openTable("my_table");
|
||||
```
|
||||
|
||||
## Adding to a Table
|
||||
After a table has been created, you can always add more data to it using
|
||||
|
||||
=== "Python"
|
||||
You can add any of the valid data structures accepted by LanceDB table, i.e, `dict`, `list[dict]`, `pd.DataFrame`, or a `Iterator[pa.RecordBatch]`. Here are some examples.
|
||||
|
||||
### Adding Pandas DataFrame
|
||||
|
||||
```python
|
||||
df = pd.DataFrame({
|
||||
"vector": [[1.3, 1.4], [9.5, 56.2]], "item": ["fizz", "buzz"], "price": [100.0, 200.0]
|
||||
})
|
||||
tbl.add(df)
|
||||
```
|
||||
|
||||
You can also add a large dataset batch in one go using Iterator of any supported data types.
|
||||
|
||||
### Adding to table using Iterator
|
||||
|
||||
```python
|
||||
def make_batches():
|
||||
for i in range(5):
|
||||
yield [
|
||||
{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
|
||||
{"vector": [5.9, 26.5], "item": "bar", "price": 20.0}
|
||||
]
|
||||
tbl.add(make_batches())
|
||||
```
|
||||
|
||||
The other arguments accepted:
|
||||
|
||||
| Name | Type | Description | Default |
|
||||
|---|---|---|---|
|
||||
| data | DATA | The data to insert into the table. | required |
|
||||
| mode | str | The mode to use when writing the data. Valid values are "append" and "overwrite". | append |
|
||||
| on_bad_vectors | str | What to do if any of the vectors are not the same size or contains NaNs. One of "error", "drop", "fill". | drop |
|
||||
| fill value | float | The value to use when filling vectors: Only used if on_bad_vectors="fill". | 0.0 |
|
||||
|
||||
|
||||
=== "Javascript/Typescript"
|
||||
|
||||
```javascript
|
||||
await tbl.add([{vector: [1.3, 1.4], item: "fizz", price: 100.0},
|
||||
{vector: [9.5, 56.2], item: "buzz", price: 200.0}])
|
||||
```
|
||||
|
||||
## Deleting from a Table
|
||||
|
||||
Use the `delete()` method on tables to delete rows from a table. To choose which rows to delete, provide a filter that matches on the metadata columns. This can delete any number of rows that match the filter.
|
||||
|
||||
=== "Python"
|
||||
|
||||
```python
|
||||
tbl.delete('item = "fizz"')
|
||||
```
|
||||
|
||||
### Deleting row with specific column value
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
|
||||
data = [{"x": 1, "vector": [1, 2]},
|
||||
{"x": 2, "vector": [3, 4]},
|
||||
{"x": 3, "vector": [5, 6]}]
|
||||
db = lancedb.connect("./.lancedb")
|
||||
table = db.create_table("my_table", data)
|
||||
table.to_pandas()
|
||||
# x vector
|
||||
# 0 1 [1.0, 2.0]
|
||||
# 1 2 [3.0, 4.0]
|
||||
# 2 3 [5.0, 6.0]
|
||||
|
||||
table.delete("x = 2")
|
||||
table.to_pandas()
|
||||
# x vector
|
||||
# 0 1 [1.0, 2.0]
|
||||
# 1 3 [5.0, 6.0]
|
||||
```
|
||||
|
||||
### Delete from a list of values
|
||||
|
||||
```python
|
||||
to_remove = [1, 5]
|
||||
to_remove = ", ".join(str(v) for v in to_remove)
|
||||
|
||||
table.delete(f"x IN ({to_remove})")
|
||||
table.to_pandas()
|
||||
# x vector
|
||||
# 0 3 [5.0, 6.0]
|
||||
```
|
||||
|
||||
=== "Javascript/Typescript"
|
||||
|
||||
```javascript
|
||||
await tbl.delete('item = "fizz"')
|
||||
```
|
||||
|
||||
### Deleting row with specific column value
|
||||
|
||||
```javascript
|
||||
const con = await lancedb.connect("./.lancedb")
|
||||
const data = [
|
||||
{id: 1, vector: [1, 2]},
|
||||
{id: 2, vector: [3, 4]},
|
||||
{id: 3, vector: [5, 6]},
|
||||
];
|
||||
const tbl = await con.createTable("my_table", data)
|
||||
await tbl.delete("id = 2")
|
||||
await tbl.countRows() // Returns 2
|
||||
```
|
||||
|
||||
### Delete from a list of values
|
||||
|
||||
```javascript
|
||||
const to_remove = [1, 5];
|
||||
await tbl.delete(`id IN (${to_remove.join(",")})`)
|
||||
await tbl.countRows() // Returns 1
|
||||
```
|
||||
|
||||
## Updating a Table
|
||||
|
||||
This can be used to update zero to all rows depending on how many rows match the where clause. The update queries follow the form of a SQL UPDATE statement. The `where` parameter is a SQL filter that matches on the metadata columns. The `values` or `values_sql` parameters are used to provide the new values for the columns.
|
||||
|
||||
| Parameter | Type | Description |
|
||||
|---|---|---|
|
||||
| `where` | `str` | The SQL where clause to use when updating rows. For example, `'x = 2'` or `'x IN (1, 2, 3)'`. The filter must not be empty, or it will error. |
|
||||
| `values` | `dict` | The values to update. The keys are the column names and the values are the values to set. |
|
||||
| `values_sql` | `dict` | The values to update. The keys are the column names and the values are the SQL expressions to set. For example, `{'x': 'x + 1'}` will increment the value of the `x` column by 1. |
|
||||
|
||||
!!! info "SQL syntax"
|
||||
|
||||
See [SQL filters](sql.md) for more information on the supported SQL syntax.
|
||||
|
||||
!!! warning "Warning"

When rows are updated, they are moved out of the index. The row will still show up in ANN queries, but the query will not be as fast as it would be if the row was in the index. If you update a large proportion of rows, consider rebuilding the index afterwards.

Basic recipe
|
||||
____________
|
||||
|
||||
The basic workflow to use LanceDB to create a similarity index on your FiftyOne
|
||||
datasets and use this to query your data is as follows:
|
||||
|
||||
1) Load a dataset into FiftyOne
|
||||
|
||||
2) Compute embedding vectors for samples or patches in your dataset, or select
|
||||
a model to use to generate embeddings
|
||||
|
||||
3) Use the `compute_similarity()`
|
||||
method to generate a LanceDB table for the samples or object
|
||||
patches embeddings in a dataset by setting the parameter `backend="lancedb"` and
|
||||
specifying a `brain_key` of your choice
|
||||
|
||||
4) Use this LanceDB table to query your data with
|
||||
`sort_by_similarity()`
|
||||
|
||||
5) If desired, delete the table
|
||||
|
||||
The example below demonstrates this workflow.
|
||||
|
||||
!!! Note
|
||||
|
||||
You must install the LanceDB Python client to run this
|
||||
```
|
||||
pip install lancedb
|
||||
```
|
||||
|
||||
```python
|
||||
|
||||
import fiftyone as fo
|
||||
import fiftyone.brain as fob
|
||||
import fiftyone.zoo as foz
|
||||
|
||||
# Step 1: Load your data into FiftyOne
|
||||
dataset = foz.load_zoo_dataset("quickstart")
|
||||
|
||||
# Steps 2 and 3: Compute embeddings and create a similarity index
|
||||
lancedb_index = fob.compute_similarity(
|
||||
dataset,
|
||||
model="clip-vit-base32-torch",
|
||||
brain_key="lancedb_index",
|
||||
backend="lancedb",
|
||||
)
|
||||
```
|
||||
Once the similarity index has been generated, we can query our data in FiftyOne
|
||||
by specifying the `brain_key`:
|
||||
|
||||
```python
|
||||
# Step 4: Query your data
|
||||
query = dataset.first().id # query by sample ID
|
||||
view = dataset.sort_by_similarity(
|
||||
query,
|
||||
brain_key="lancedb_index",
|
||||
k=10, # limit to 10 most similar samples
|
||||
)
|
||||
|
||||
# Step 5 (optional): Cleanup
|
||||
|
||||
# Delete the LanceDB table
|
||||
lancedb_index.cleanup()
|
||||
|
||||
# Delete run record from FiftyOne
|
||||
dataset.delete_brain_run("lancedb_index")
|
||||
```

### Output formats
|
||||
|
||||
LanceDB returns results in many different formats commonly used in python.
|
||||
Let's create a LanceDB table with a nested schema:
|
||||
|
||||
```python
|
||||
from datetime import datetime
|
||||
import lancedb
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
import numpy as np
|
||||
from pydantic import BaseModel
|
||||
uri = "data/sample-lancedb-nested"
|
||||
|
||||
class Metadata(BaseModel):
|
||||
source: str
|
||||
timestamp: datetime
|
||||
|
||||
class Document(BaseModel):
|
||||
content: str
|
||||
meta: Metadata
|
||||
|
||||
class LanceSchema(LanceModel):
|
||||
id: str
|
||||
vector: Vector(1536)
|
||||
payload: Document
|
||||
|
||||
# Let's add 100 sample rows to our dataset
|
||||
data = [LanceSchema(
|
||||
id=f"id{i}",
|
||||
vector=np.random.randn(1536),
|
||||
payload=Document(
|
||||
content=f"document{i}", meta=Metadata(source=f"source{i%10}", timestamp=datetime.now())
|
||||
),
|
||||
) for i in range(100)]
|
||||
|
||||
tbl = db.create_table("documents", data=data)
|
||||
```
|
||||
|
||||
#### As a pyarrow table
|
||||
|
||||
Using `to_arrow()` we can get the results back as a pyarrow Table.
|
||||
This result table has the same columns as the LanceDB table, with
|
||||
the addition of an `_distance` column for vector search or a `score`
|
||||
column for full text search.
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_arrow()
|
||||
```
|
||||
|
||||
#### As a pandas dataframe
|
||||
|
||||
You can also get the results as a pandas dataframe.
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_pandas()
|
||||
```
|
||||
|
||||
While other formats like Arrow/Pydantic/Python dicts have a natural
|
||||
way to handle nested schemas, pandas can only store nested data as a
|
||||
python dict column, which makes it difficult to support nested references.
|
||||
So for convenience, you can also tell LanceDB to flatten a nested schema
|
||||
when creating the pandas dataframe.
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_pandas(flatten=True)
|
||||
```
|
||||
|
||||
If your table has a deeply nested struct, you can control how many levels
|
||||
of nesting to flatten by passing in a positive integer.
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_pandas(flatten=1)
|
||||
```
|
||||
|
||||
|
||||
#### As a list of python dicts
|
||||
|
||||
You can of course return results as a list of python dicts.
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_list()
|
||||
```
|
||||
|
||||
#### As a list of pydantic models
|
||||
|
||||
We can add data using pydantic models, and we can certainly
|
||||
retrieve results as pydantic models
|
||||
|
||||
```python
|
||||
tbl.search(np.random.randn(1536)).to_pydantic(LanceSchema)
|
||||
```
|
||||
|
||||
Note that in this case the extra `_distance` field is discarded since
|
||||
it's not part of the LanceSchema.
|
||||
|
||||
|
||||
