Default: False Infinite losses mainly occur when the inputs are too short to be aligned to the targets. You need to do that in your code : model = Wav2Vec2ForCTC.from_pretrained (path_2_model)

Because these weights are multiplied along with the layers in the backpropagation phase. ... Understand fan_in and fan_out mode in Pytorch implementation. nn.init.kaiming_normal_() will return tensor that has values sampled from mean 0 and variance std. There are two … WebMay 14, 2024 · I used Gradient Clipping to overcome this problem in the linked notebook. Gradient clipping will ‘clip’ the gradients or cap them to a threshold value to prevent the gradients from getting too large. In PyTorch you can do this with one line of code. torch.nn.utils.clip_grad_norm_(model.parameters(), 4.0) Here 4.0 is the threshold. the hemby trust
