Fix NotImplementedError
in LanceDB
✅ Solution
The "NotImplementedError" in LanceDB usually arises when attempting to use a feature that is either unavailable in the specific LanceDB deployment (cloud vs. local) or has not yet been implemented in the Python client. To resolve this, confirm the desired feature (e.g., namespaces, certain index types, full-text search) is supported in your LanceDB environment; if not, consider using a supported alternative or check for updates to the LanceDB client library if it's a missing feature in the client. For cloud versions, check the available features supported.
