Additional Information

• I'm using the latest version of Python (3.12.6).
• Both precompiled and manually installed version give me this error.
• I tried uninstalling Applio completely and reinstalling it, but I still get the error.

disable upscale option

[MarcoFederici1999]

disable upscale option

The upscaler was and is disabled, yet Applio tries to interact with it nonetheless.

Additional Information I'm using the latest version of Python (3.12.6).

Yeah.. about that. Use 3.10

I switched to 3.10 as you suggested but I still get the error.

[blaisewf]

could you try with the compiled version?

Since the error happens from the simple import (regardless whether upscale is used or not), the likely issue is an actually damaged model config.

Try looking for "models--roberta-base" folder under C:\users\xxxx\.cache\huggingface\hub and deleting it.

Yes, apparently this was the issue, I'm not really sure what caused it to be damaged though.
