mel() error

[EricKong1985]

when I run the project in the colab,

i will show the error below:

Using cuda for inference.

Don't know if it will helpful for you but I have created a repository that fixes the running for inference using the pretrained model. here is the link https://github.com/HassanMuhammadSannaullah/Wav2lip-Fix-For-Inference

pip install librosa == 0.8.0

when using librosa>=0.10.0, you should fix “_build_mel_basis()” in audio.py

def _build_mel_basis():
    assert hp.fmax <= hp.sample_rate // 2
    return librosa.filters.mel(sr=hp.sample_rate, n_fft=hp.n_fft, n_mels=hp.num_mels,
                               fmin=hp.fmin, fmax=hp.fmax)

def _build_mel_basis():
    assert hp.fmax <= hp.sample_rate // 2
    return librosa.filters.mel(sr=hp.sample_rate, n_fft=hp.n_fft, n_mels=hp.num_mels,
                               fmin=hp.fmin, fmax=hp.fmax)

Thanks for sharing, this change works for me

You're a lifesaver! Thank you very much :)
