Validation data missing ids?

Tournament

Hi! I’m trying to get back to Numerai after a long time. I noticed that there are no ids in the validation data. It’s just [None] when I try to print index or id fields. Is this some bug or is there a reason why ids have been stripped from validation data? Maybe I’m missing something here.

I’m asking about the ids because I want to diagnose my new models using the validation data. The diagnostic tool of course doesn’t accept the CSVs with empty id fields.

validation.parquet file (there are no CSV validation files) have id column used as index. So, if you are converting it to CSV, you should do it like

valid_df = pandas.read_parquet(path_to_validation_parquet)
valid_df.to_csv(path_to_validation_csv, index=True)

Please mention that index param is default True, so it could be omitted.
