traindata = load_dataset('wikitext', 'wikitext-2-raw-v1', split='train')

ds = builder_instance.as_dataset(split=split, verification_mode=verification_mode, in_memory=keep_in_memory)
File "/home/aelkordy/.conda/envs/prune_llm/lib/python3.9/site-packages/datasets/builder.py", line 1108, in as_dataset

This error stems from a breaking change in fsspec. It has been fixed in the latest datasets release (2.14.6). Updating the installation with pip install -U datasets should fix the issue.

Fixed by:

• datasets.filesystems: fix is_remote_filesystems #6334

The fix was released in datasets-2.14.6.

[dhruv-anand-aintech]

this is fixed in 2.15.0, but broken again in 2.17.0. Can someone verify?

[jgontrum]

I'm on 2.17.1 and can confirm it's broken again. Downgrading to 2.16 helped.

[Mariemomezzine]

2.14.6

i update the version but the error still exist

[JPonsa]

The issue seems to persist in 2.18.0

[GoGoZeppeli-towa]

same problem in 2.18.0

[lhoestq]

Which version of fsspec and OS are you using ?

[GoGoZeppeli-towa]

Which version of fsspec and OS are you using ?

fsspec-2023.10.0 and Windows 10, guess fsspec version too old...
