Comments:
Hi ! Are you sure you have `datasets` 2.16 ? I just checked and on 2.16 I can run `from datasets.arrow_writer import SchemaInferenceError` without error

I have the same issue - using with datasets version 2.16.1. Also this is on a kaggle notebook - other people with the same issue also seem to be having it on kaggle?

I have the same issue now and didn't have this problem around 2 weeks ago.

Yes, I am sure

Don't know about other people. But I am having this issue whose solution I can't find anywhere. And this issue still persists.

Same here

I was having the same issue but the datasets version was 2.6.1, after I updated it to latest(2.16), error is gone while importing.

I also have datasets version 2.16, but the error is still there.

Can you try re-installing `datasets` ?

I tried re-installing. Still getting the same error.

In kaggle I used:
- `%pip install -U datasets`
and then restarted runtime and then everything works fine.

Yes, this is working. When I restart the runtime after installing packages, it's working perfectly. Thank you so much. But why do we need to restart runtime every time after installing packages?

For some packages it is required.

Thank you for your assistance. I dedicated the past 2-3 weeks to resolving this issue. Interestingly, it runs flawlessly in Colab without requiring a runtime restart. However, the problem persisted exclusively in Kaggle. I appreciate your help once again. Thank you.

Closing this issue as it is not related to the datasets library; rather, it's linked to platform-related issues.
