Fix NoDataError

in Polars

Solution

NoDataError in Polars often arises when operations, like CSV parsing or data filtering, result in an empty DataFrame, and `raise_if_empty=True` (the default). Fix this by setting `raise_if_empty=False` during operations like `scan_csv` or `read_csv` to return an empty DataFrame gracefully, or ensure the input data isn't empty if an empty frame is not desired, and make sure to properly infer the schema or provide one.
