I meant using pyarrow to load the files generated by dataset, I tried that
and it fails with the same error as in R with both pyarrow 15 and 17:
```
pyarrow.feather.read_feather("~/.cache/huggingface/datasets/squad/plain_text/0.0.0/7b6d24c440a36b6815f21b70d25016731768db1f/squad-train.arrow")
Traceback (most recent call last):
...
File "pyarrow/_feather.pyx", line 79, in
pyarrow._feather.FeatherReader.__cinit__
File "pyarrow/error.pxi", line 155, in
pyarrow.lib.pyarrow_internal_check_status
File "pyarrow/error.pxi", line 92, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Not a Feather V1 or Arrow IPC file
```
After perusing the dataset source it turns out that they are using the ipc
stream format https://github.com/huggingface/datasets/pull/1933
So you can use `arrow::read_ipc_stream("path/to/file.arrow")` to open it in
R.
