CogVideoXWrapper Import failed

[ebelharw]

Hi! I'm having trouble importing CogVideoXWrapper, it's giving me (IMPORT FAILED) in the Manager and "Try Fix" doesn't seem to do anything. I'm still pretty new to all this so I'm not sure what to make of this error in the log, any insight would be greatly appreciated:

File "C:\Users\webelhar\Desktop\ComfyUI_windows_portable\python_embeded\Lib\site-packages\diffusers\utils\import_utils.py", line 855, in _get_module

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

Thanks for your time!

Looks like transformers version error, should try updating that, at least for me the nodes import with the latest version fine.
