Hi @wqh17101 - thanks for opening this PR with a solution! As this is a highly specific fix (adding in an environment variable to control logic for a single issue), it's not something we're going to merge in right now. 

The great thing about open source is that you can modify the original repo as you wish with your own fork to include this code. 

This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.

Please note that issues that do not follow the [contributing guidelines](https://github.com/huggingface/transformers/blob/main/CONTRIBUTING.md) are likely to be ignored.

Any updates on this? I can't install `flash_attn` in my environment, and I want to skip the `check_imports` when loading models. What should I do?
