### Expected behavior

can't load dataset

### Environment info

dataset:samsum
system :win10
gpu:m40 24G

Hi @Hughhuh. 

I have formatted the issue because it was not easily readable. Additionally, the environment info is incomplete: it seems you did not run the proposed CLI command `datasets-cli env` and essential information is missing: version of `datasets`, version of `pyarrow`,...

With the information you provided, it seems an issue with the specific "samsum" dataset. I'm transferring the issue to the corresponding dataset page: https://huggingface.co/datasets/samsum/discussions/5
