any parquet i queried returned same error, so i created venv with python3.6.9 and now i get following error:

Traceback (most recent call last):

    from dataclasses import dataclass
ModuleNotFoundError: No module named 'dataclasses'

ok i installed dataclasses and it works, closing issue

@jan-kwiatkowski Thank you for making issue.

I couldn't reproduce your problem in my machine.
Please give me some information about

• command you run
• traceback
• parquet file

I tried again with python 3.6 and it worked sorry for inconvenience.
