Problem loading datasets library from Kaggle

🤗Datasets

After installing datasets and import it in Kaggle (with TPU support, no acceleration environment is ok), I received this warning message:

---------------------------------------------------------------------------

ValueError: pyarrow.lib.Codec size changed, may indicate binary incompatibility. Expected 48 from C header, got 40 from PyObject

Seems to be updating pyarrow-5.0.0 from pyarrow-4.0.0>?
I tried to uninstall and install again with no help. any ideas? Thanks

Hi,

make sure to restart the kernel after installing datasets and then it should work.

Thanks restart the kernel works!

I ran into this issue too, and I’m wondering if it is possible to run the notebook using “Save Version.” Since the kernel can’t be restarted after hitting “Save Version”, I don’t think it is possible, right?

It’s possible to fix the issue on kaggle by using no-deps while installing datasets. But you need to install xxhash and huggingface-hub first. This way pyarrow is not reinstalled.

I don’t this is an issue anymore because it seems like Kaggle includes datasets by default. I even made a notebook about it:

Thanks. I guess my notebooks were running on an older VM.
