WebIndeed from the doc of CTCLoss (pytorch): ``'mean'``: the output losses will be divided by the target lengths and then the mean over the batch is taken. To obtain the same value: 1- Change the reduction method to sum: ctc_loss = nn.CTCLoss (reduction='sum') 2- Divide the loss computed by the batch_size: WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.

Does anyone know the true? Tutorial code is located below. import torch from torch_baidu_ctc import ctc_loss, CTCLoss # Activations. 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 ... easter studio pictures
