Reproduction

This GitHub issue is not about resolving the errors below, it's about a logical error in the code that produces the errors.

I get the following error running some code:

ImportError: This modeling file requires the following packages that were not found in your environment: flash_attn.

But I have flash_attn installed. The underlying problem is that when importing flash_attn, some other code throws an ImportError, but that error is swallowed by transformers code.

To be specific, the logical mistake is in the check_imports function. It assumes that if you get an ImportError when trying to import a package, it means that the package isn't installed.

That's probably a fine assumption most of the time, but when something's going wrong like in my case, it makes it hard to find out what because the real error is being swallowed and replaced. This is the real error, by the way:

ImportError: libcudart.so.11.0: cannot open shared object file: No such file or directory

To reiterate, this issue is not about resolving these errors, it's about fixing the code that masks useful errors (although it someone happens to know the fix, great).

Expected behavior

You should show the original error and then if you want to, also show the hand-written "missing packages" message.
