cannot import name 'Undefined' from 'pydantic.fields' Error

[afk22]

I can use stable diffusion without any problems. However, whenever I try to install ControlNet, I encounter the error below and can't use the program. I've reinstalled the program from scratch, but it didn't fix the issue. I tried "pip install --upgrade pip" but it didn't work either. Most of the solutions I found online didn't help.

File "C:\Users\AFK\Downloads\sd.webui\system\python\lib\site-packages\fastapi\params.py", line 4, in
from pydantic.fields import FieldInfo, Undefined
ImportError: cannot import name 'Undefined' from 'pydantic.fields' (C:\Users\AFK\Downloads\sd.webui\system\python\lib\site-packages\pydantic\fields.py)
Press any key to continue . . .

Hi @afk22! I had the same problem and someone awesome helps me with this in a Discord group, it works!!!

1. First of all you need to have pip installed.
2. Open and explorer window and go to the folder of your SD ...\stable-diffusion-webui\venv\Scripts
3. Type "CMD" in the address bar.
4. Write in the console: activate
5. Write: cd.. two times to arrive at your stable-diffusion-webui directory
6. Write: pip install -r requirements.txt

And that´s all! I hope it works :)
