OSError: Consistency check failed: file should be of size 301736502 but has size 293192246 (0002.parquet).
We are sorry for the inconvenience. Please retry download and pass `force_download=True, resume_download=False` as argument.
If the issue persists, please let us know by opening an issue on https://github.com/huggingface/huggingface_hub.

See that there is an error in hf_hub_download, It looks like the library tried to compare the file with a previous one in the local cache. Maybe the data changed or there was a previously downloaded obsolete/corrupted file.
I think we should force-download each time to always have a refreshed parquet file.

I will merge this PR since looks like the e2e failed check is not related to this code.
I was able to run the tests locally
