actually there was already a thread about this, someone found a temporary fix i tried it and it worked. here is the link https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/15551

Some lib is not download/install it`s seem like, last month i got some issue;

[ucandoit74]

I also had the same problem. How do I solve this?

[w-e-w]

downgrading pydantic to 1.10.15 and albumentations to 1.4.3

the can be done by running a pip command in the webui's python environment

from the webui root the following commands if using powershell on windwos

.\venv\Scripts\Activate.ps1
pip install albumentations==1.4.3
pip install pydantic==1.10.15

if using cmd on windows

venv\Scripts\activate
pip install albumentations==1.4.3
pip install pydantic==1.10.15

if using linux

source venv/bin/activate
pip install albumentations==1.4.3
pip install pydantic==1.10.15

I solved it by reinstalling Automatic1111 again with Windows :)

Hello, I just solved the problem. It seems that the issue might be due to the version incompatibility between the Pydantic version used and the version referenced in the code where "Undefined" is being used.

To address this issue, I tried resetting the virtual environment. You can manually delete the venv folder in the directory and then create a new venv folder in the same directory. Then activate the virtual environment:

venv\Scripts\activate

After activation, restart webui-user.bat and wait for the new dependencies to be installed. Then, downgrade Pydantic to the version 1.10.15:

pip install pydantic==1.10.15

After that, run webui-user.bat again, and everything should work fine.

I hope this helps everyone.

notice there is a update to the command that you need to run https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/15556#issuecomment-2063582512
