WebMar 10, 2024 · 这是因为在PyTorch中,backward ()函数需要传入一个和loss相同shape的向量,用于计算梯度。. 这个向量通常被称为梯度权重,它的作用是将loss的梯度传递给网络中的每个参数。. 如果没有传入梯度权重,PyTorch将无法计算梯度,从而无法进行反向传播。. WebMay 1, 2024 · The loss can be used for efficiently training a model without using a time-consuming AR structure because the STFT spectrum can contain multiple speech waveform samples and because a waveform...
