I understand that Pandas can read and write to and from Parquet files using different backends: pyarrow and fastparquet.

I have a Conda distribution with the Intel distribution and "it works": I can use pandas.DataFrame.to_parquet. However I do not have pyarrow installed so I guess that fastparquet is used (which I cannot find either).

Is there a way to identify which backend is used?
