### Who can help?

_No response_

### Information

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

### Tasks

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

### Reproduction

Create a file `a.py` with the following content

```python
from transformers import AutoConfig
AutoConfig.from_pretrained("THUDM/glm-10b", trust_remote_code=True)
```

Run it with `torchrun`

```
torchrun --nproc-per-node 8 a.py
```

Then we would get this error sometimes

```

It seems that it is a multiprocess-relalted issue. 
https://github.com/huggingface/transformers/blob/v4.27.4/src/transformers/dynamic_module_utils.py#L147-L179

### Expected behavior

Dynamic module can be imported successfully when using ddp.

Thanks for raising this issue. I think this is linked to #21646, I will push a fix shortly.
