### Describe the bug

When I run the following code I get an exception;
`go_emotions = load_dataset("go_emotions")`

### Steps to reproduce the bug

```
from datasets import load_dataset
go_emotions = load_dataset("go_emotions")
```

### Expected behavior

Should simply load the variable with the data from the file

Comments:
Thanks for reporting, @arame.

I guess you have an old version of `transformers` (that submodule is present in `transformers` since version 3.0.1, since nearly 4 years ago). If you update it, the error should disappear:
```shell
pip install -U transformers
```

On the other hand, I am wondering: does it make sense to use `transformers` in this case, even if we don't need it to load the `go_emotions` dataset (already converted to Parquet files)?
- Maybe @mariosasko can give some insight, as he included these code lines:
  - #6454

The linked code lazily registers a custom reducer for `transformers.PreTrainedTokenizerBase` only if `transformers` have already been imported (imports are expensive, so we check `sys.modules`).

However, the logic does not account for `transformers<3`, so we should add a version check to fix that.

Thank you for that Mario. Would this fix solve the problem and do you have any idea when it will be done? 
I tried the pip install suggested by Albert and it made no difference.

I tried running the code today and the problem appears to be fixed.
