ValueError: mutable default <class 'fairseq.dataclass.configs.CommonConfig'> for field common is not allowed: use default_factory

I have this error when trying to execute my code.

My code is:

    output_file = "tmp_rvc_audio_"
    output_file_id = 0

    while (os.path.exists(output_file + str(output_file_id) + ".wav")):
        output_file_id += 1

    return audio_bytes

Can anyone help me fix this error?

You are using python 3.11, right?
https://github.com/RVC-Project/Retrieval-based-Voice-Conversion/blob/develop/pyproject.toml#L14-L15
Comment out L14 and uncomment L15 and install again.

I ran the command:

pip uninstall fairseq
pip install git+https://github.com/Tps-F/fairseq.git@main

And it works now, thanks for the help!
