Pydantic import error in fastapi · pydantic/pydantic · Discussion #5185
This issue originally came up as I was having issues with uvicorn but as I've been trying to work out a fix I've started getting pydantic errors. I'm running in a virtual environment using pyenv and tried multiple versions of python, so I'm guessing it must be an issue with some packages not playing well with arm64 as I'm on an M1 mac.

help, getting this error message ImportError: cannot import name 'Undefined' from 'pydantic.fields'
Looking into it, it looks like it's a version compatibility issue. https://github.com/oobabooga/text-generation-webui/issues/3850 You need to manually edit the "requirements.txt", line 2 - change it to "fastapi==0.103.1". "gradio_client==0.5.0" then: pip install --upgrade gradio . This may be a dumb question, but are you running it from the same location? Oobabooga, the way it is installed, looks for files in specific folders in relation to the Oobabooga install. Open the "cmd_windows.bat" file. This will open up the CMD prompt in the appropriate environment. Type "pip show pydantic" This will confirm whether pydantic is installed in the environment. If you're still having trouble, copy the entire block that traces the error. More on reddit.com

September 10, 2023 -

Hi, my Oobabooga installation suddenly stop working today. It was working fine yesterday and today I am getting this error:

ImportError: cannot import name 'Undefined' from 'pydantic.fields' E:\Oobabooga\installer_files\env\lib\site-packages\pydantic\fields.py)

I am on windows and don't know much about linux or python. I already tried update a couple of times and it's saying I am up to date. Any idea for a quick fix?

[Fixed] ModuleNotFoundError: No module named ‘pydantic’ – Be on the Right Side of Change
June 12, 2022 - Quick Fix: Python raises the ImportError: No module named 'pydantic' when it cannot find the library pydantic. The most frequent source of this error is that you haven’t installed pydantic explicitly with pip install pydantic. Alternatively, you may have different Python versions on your computer, and pydantic is not installed for the particular version you’re using.
