声码器一般训练多久？看什么参数？ Epoch: 95 Steps : 3670, Gen Loss Total : 25.942, Mel-Spec. Error : 0.381, s/b : 1.108 Steps : 3675, Gen Loss Total : 27.207, Mel-Spec. Error : 0.382, s/b : 1.116 Steps : 3680, Gen Loss Total : 26.531, Mel-Spec. Error : 0.383, s/b : 1.109 Steps : 3685, Gen Loss Total : 27.694, Mel-Spec. Error : 0.389, s/b : 1.118 Steps : 3690, Gen Loss Total : 25.060, Mel-Spec. Error : 0.368, s/b : 1.112 Steps : 3695, Gen Loss Total : 25.569, Mel-Spec.

训练hifigan声码器遇到了问题
spec = torch.stft(y, n_fft, hop_length=hop_size, win_length=win_size, window=hann_window[str(y.device)],
center=center, pad_mode='reflect', normalized=False, onesided=True, return_complex=False) #
spec = torch.sqrt(spec.pow(2).sum(-1)+(1e-9))
后spec的输出已经为[nan][nan][nan]了，导致后续在计算loss的时候就全部为nan了
