Another question: Currently I’ve set hidden size to 128 (matching both input_size and num_clasees) - if I change it hidden_size=100, now the dimensions won’t match, leading to this error:

Target size (torch.Size([1, 226, 128])) must be the same as input size (torch.Size([1, 226, 100]))

But since the dimensions on the outputs and target should match, how can I change the hidden_size without affecting the relationship between output/target? @ptrblck
