Fix: Control-Net; ImportError; Undefined; pydantic; insightface

[w-e-w]

Error

ImportError: cannot import name 'Undefined' from 'pydantic.fields'

Currently there is an issue with new installation of Control Net breaking WebUI

this is caused by a recent update to Control-Net's Upstream dependency albumentations 1.4.4 see history
in albumentations==1.4.4 they introduce a new dependency requirement

• pydantic required: >=2.6.4

albumentations is installed by insightface which specifies Any version of albumentations as such pip install the latest version of albumentations==1.4.4

this issue is that WebUi 1.7~1.9 with Gradio==3.41.2 uses fastapi==0.94.0 which requires

• pydantic required: >=1.7.4,<3.0.0,!=2.0.1,!=2.0.0,!=1.8.1,!=1.8

as such the Upstream update of albumentations causes WebUi to break

Any other extensions that also uses insightface will also be affected with the same issue

• note for dev: pydantic requirement may change after Gradio 4 #14184

User Fix method one

downgrading pydantic to 1.10.15 and albumentations to 1.4.3
this can be done by running the following 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

User Fix method two

Since sd-webui-controlnet has updated a fix to this issue there is an alternative method to solve this issue

this method is not as efficient as method one but hopefully it's easier to follow for those who do not know the way around terminal; python; venv; pip

1. add --disable-extra-extensions to COMMANDLINE_ARGS in webui-user.bat or webui-user.sh
2. delete venv
3. start webui using webui-user.bat or webui.sh
4. update controlnet using extensions tab
5. close webui
6. remove --disable-extra-extensions from COMMANDLINE_ARGS in webui-user.bat
7. relaunch webui

as far as I'm aware this is already a fixed issue

if you're still experiencing similar issues but most likely is something else or you haven't performed a fixed properly
I'm assuming that it isn't caused by a new issue

run the command

pip freeze

the post the result

I'll also need a list a list of your extensions
