Your model predicts 28 classes, therefore the output of the model has size [batch_size, seq_len, 28] (or [seq_len, batch_size, 28] for the log probabilities that are given to the CTC loss). In the nn.CTCLoss you set blank=28, which means that the blank label is the class with index 28. To get the log probabilities for the blank label ... rwandan currency to ksh https://lamontjaxon.com
