Fix ArrowNotImplementedError

✅ Solution

ArrowNotImplementedError in Polars usually arises from compatibility issues between the Arrow library used by Polars and specific data types or features in your Parquet files or schemas. To fix this error, ensure your pyarrow version is compatible with the polars version and that pyarrow supports all datatypes present in your Parquet file; consider updating pyarrow or casting questionable columns (e.g., using `pl.col("my_col").cast(pl.Utf8)`) to more standard types before writing or reading your data. You may also need to explicitly specify the Arrow schema using `use_pyarrow=True` to control data type handling.
