Fix ModuleNotFoundError
in LanceDB
✅ Solution
ModuleNotFoundError typically arises when a required Python package is not installed in your environment, or when the PYTHONPATH is not correctly set. To fix this, first ensure the missing module (e.g., lance, numpy) is installed using `pip install <module_name>`. If the error persists, verify your Python environment and PYTHONPATH are configured correctly to include the installation path of the missing module.
