Importing transformers in ipython throws error due to `_pytest`
### System Info

- PyTorch version (GPU?): 2.0.1 (False)
- Tensorflow version (GPU?): not installed (NA)
- Flax version (CPU?/GPU?/TPU?): not installed (NA)
- Jax version: not installed

### Who can help?

_No response_

### Information

- [ ] The official example scripts
- [ ] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

typing `from transformers.` and then pressing `TAB` (i.e., autocompletion) shows the following stack trace in `ipython`. Aftwards, everything works as expected, although trying to use anything from `transformers.testing_utils` will throw the same error. This happens because `ipython` is doing introspection of the testing module, which then attempts to import the `_pytest` module, which doesn't exist.

The above exception was the direct cause of the following exception:

### Expected behavior

A possible workaround would be to use a try-except statement around this block, which then prints a useful error message.
I have exactly same issue with this, how to resolve the issue? <|||||>I have the same issue with the 4.30.0 version.

I am also seeing this error. I just hacked out the use of the CapturLogger in the example run_clm.

Since this bug is closed, should we open a different one with this issue?<|||||>@asampat3090 @sei-amellinger 

@amyeroberts 's fix #24241 is merged after the tag `v4.31.0.dev0`. So the first thing to check is to see what the commit you have used to install `transformers`. In any case, you can fetch the latest commit and install it again. It should work fine I think. <|||||>pip3 uninstall pytest
pip3 install pytest

maybe pytest version is old<|||||>> maybe pytest version is old

Yeah, it was on old version of pytest.

Thanks!<|||||>Hi team, when will there be a new release that contains the fix from https://github.com/huggingface/transformers/pull/24241?

cc @sgugger<|||||>The next release will be early next week, probably on Tuesday.<|||||>Thank you!
