Unmilan Mukherjee 75c5c83f12 fix(python): resolve Ollama embedding serialization error in create_table (#3583)
This PR fixes a serialization error when using Ollama embeddings in
`create_table`.

The use of `@cached_property` for the Ollama client was causing issues
during serialization/pickling, which is required by certain LanceDB
operations (like when using multiprocessing or certain storage
backends). Switching to a standard `@property` ensures the client is
instantiated when needed without being stored in a way that breaks
serialization.

Verified with the following script:
```python
import lancedb
from lancedb.embeddings import get_registry
import pickle

registry = get_registry().get(\"ollama\")
model = registry(name=\"llama3\")

# This would fail before the fix
pickled = pickle.dumps(model)
unpickled = pickle.loads(pickled)
```

Fixes #2629 (or similar serialization issues reported).

LanceDB Python SDK

A Python library for LanceDB.

Installation

pip install lancedb

Preview Releases

Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.

pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb

Usage

Basic Example

import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')
table = db.open_table('my_table')
results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
