Fix ArrowNotImplementedError

in Pandas

Solution

ArrowNotImplementedError in pandas arises when attempting operations with data types or functionalities not yet supported by the underlying pyarrow library when using `dtype="pyarrow"`. Solutions include: converting the pandas Series/DataFrame column to a compatible NumPy dtype (e.g., using `.astype("float64")` or `.astype("string")` if applicable before the operation, or avoiding `dtype="pyarrow"` where arrow functionality is incomplete. If support is expected or needed, ensure you're using the latest pyarrow version; otherwise, report the feature request to the pandas or pyarrow project.
