Ctcloss zero_infinity

WebMar 20, 2024 · A few problems can be seen from the result (besides the problem mentioned aboved and the problem with CuDNN implementation as noted in #21680 ): the CPU implementation does not respect zero_infinity when target is empty (see the huge loss in test 2 with zero_info=True); the non-CuDNN CUDA implementation will hang when all … Webloss = torch.nn.CTCLoss(blank=V, zero_infinity= False) acoustic_seq, acoustic_seq_len, target_seq, target _seq_len = get_sample(T, U, V) ... In the PyTorch specific implementation of CTC Loss, we can specify a flag zero_infinity, which explicitly checks for such cases, zeroes out the loss and the gradient if such a case occurs. The flag allows ...

WebWhen use mean, the output losses will be divided by the target lengths. zero_infinity. Sometimes, the calculated ctc loss has an infinity element and infinity gradient. This is common when the input sequence is not too much longer than the target. In the below sample script, set input length T = 35 and leave target length = 30.
