Weird, I refreshed and got the same error:

[Errno 39] Directory not empty: '/storage/hf-datasets-cache/medium/datasets/92601609631952-config-parquet-and-info-mikehemberger-medicinal-p-abb399f3/mikehemberger___medicinal-plants/default-697ad16f67c3c36b/0.0.0/7b7ce5247a942be131d49ad4f3de5866083399a0f250901bd8dc202f8c5f7ce5.incomplete'

maybe ping @lhoestq on this one.

The actual error is

it looks like a pyarrow bug

Hi @lhoestq ,
Scary error message. I hope I’m not to blame…
Will it complicate matters if I work on this dataset further, ie add labels etc. and push it back to the hub? Otherwise I’ll leave this is as.

You're not to blame at all ^^'
I'm also having trouble reproducing the error, which makes this bug harder to understand and report to the Apache Arrow team.
I'll continue my investigation and hopefully find a workaround

Cool, thank you. I’ll keep my hands off of this dataset for now.
Good luck :)
