Original GitHub issue: https://github.com/SillyTavern/SillyTavern-Extras/issues/240

P.S. I used a translator to translate my problem from my language into English

I'm using Windows 10

For some reason, when I try to use rvc it crashes in my console with such an error (given below) and on the same page error 500 does anyone know how to fix it? (I've checked the topic and even the topics with the same blend, nothing helped me from what I've seen)

AttributeError: module 'ffmpeg' has no attribute 'input'

### Same Issue

File "D:\anaconda3\envs\xtras\Lib\site-packages\torch\serialization.py", line 1470, in load
raise pickle.UnpicklingError(_get_wo_message(str(e))) from None
_pickle.UnpicklingError: Weights only load failed. This file can still be loaded, to do so you have two options, do those steps only if you trust the source of the checkpoint.
(1) In PyTorch 2.6, we changed the default value of the weights_only argument in torch.load from False to True. Re-running torch.load with weights_only set to False will likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source.
(2) Alternatively, to load with weights_only=True please check the recommended steps in the following error message.
WeightsUnpickler error: Unsupported global: GLOBAL fairseq.data.dictionary.Dictionary was not an allowed global by default. Please use torch.serialization.add_safe_globals([Dictionary]) or the torch.serialization.safe_globals([Dictionary]) context manager to allowlist this global if you trust this class/function.

Check the documentation of torch.load to learn more about types accepted by default with weights_only https://pytorch.org/docs/stable/generated/torch.load.html.
