ERROR: Exception in ASGI application

[Iagmon]

I just installed XTTS-Finetune-Webui, but I can't use it because when I click the "Create Dataset" I get the error below.

Reinstalling it didn't help, and looking for previous similar issues didn't help either (the only issue I found that was just like mine was closed by the same user who opened it, saying he managed to get things running after restarting the PC, but that didn't work for me).

I also got the exact same issue when I installed the XTTS-Webui, but then I downloaded the XTTS-Webui's portable version and it worked normally.

I did run the following commands, as mentioned in a similar issue, but to no avail.

pip install --upgrade pydantic==2.8.0 pip install --upgrade fastapi==0.112.4

Here's the error log:

Set arbitrary_types_allowed=True in the model_config to ignore this error or implement `__get_pydantic_core_schema` on your type to fully support it.

If you got this error by calling handler() within __get_pydantic_core_schema__ then you likely need to call handler.generate_schema(<some type>) since we do not call __get_pydantic_core_schema__ on <some type> otherwise to avoid infinite recursion.

I had a similar issue with both XTTS webui and XTTS webui finetuner. I managed to solve it for both of them, by going into xtts-webui\venv\Lib\site-packages\pydantic_internal and opening the _config.py file. In this file, I found arbitrary_types_allowed=False and changed it to arbitrary_types_allowed=True. Hope this helps.

I had the same issues and this resolved it with one small correction. The path to the file is: xtts-webui\venv\Lib\site-packages\pydantic\_internal
