> In case someone wants to load a pandas dataframe I want to share my workaround. > > For me installing `fastparquet` and specifying the `eninge='fastparquet'` argument in the `load_parquet` function worked. Concurring. If the parquet file contains a dictionary/list/struct, then the following ```python import pandas as pd df = pd.read_parquet(parquet_path) ``` throws an error "ArrowNotImplementedError: Nested data conversions not implemented for chunked array outputs" But only *if* the parquet file is over 1 GB. If it is under 1 GB, then it loads with no problems. -- This is an automated message from the Apache Git Service.
