Understanding input shape to PyTorch LSTM
问题 This seems to be one of the most common questions about LSTMs in PyTorch, but I am still unable to figure out what should be the input shape to PyTorch LSTM. Even after following several posts (1, 2, 3) and trying out the solutions, it doesn't seem to work. Background: I have encoded text sequences (variable length) in a batch of size 12 and the sequences are padded and packed using pad_packed_sequence functionality. MAX_LEN for each sequence is 384 and each token (or word) in the sequence
