pip install --upgrade transformers

I ran this "pip" command string in windows "cmd" terminal at directory F:\ComfyUI_windows_portable\python_embeded

Have you ran the command this way? (to upgrade transformers in your python embedded)

.\python.exe -m pip install --upgrade transformers

[seemon2]

Hi ..
Thanks. I tried with your command and managed to successfully install transformers-4.47.1 (previously transformers-4.42.4)
However when I tried to run my workflow, still encounter same error ..

** Error on pop up screen in comfyui.

** console log for the successful transformer pip install for reference.

Maybe you have to update diffusers as well?

i have same problem

[LukeG89]

i have same problem

@anakein If you have ComfyUI portable, you can open terminal inside python_embeded folder and run this command to update both transformers and diffusers, that should fix the issue

.\python.exe -m pip install --upgrade transformers diffusers
