Jan 14, 2021 · It is an inverse operation to pack_padded_sequence (). It pads a packed batch of variable length sequences. 1. 2. output, input_sizes = pad_packed_sequence (packed_output, batch_first=True) print(ht [-1]) The returned Tensor’s data will be of size T x B x *, where T is the length of the longest sequence and B is the batch size.
Jun 14, 2018 · In Summary: This is how you get your sanity back in PyTorch with variable length batched inputs to an LSTM. Sort inputs by largest sequence first. Make all the same length by padding to largest sequence in the batch. Use pack_padded_sequence to make sure LSTM doesn’t see padded items (Facebook team, you really should rename this API).

Each sequence has about 200K tokens on an average. The maximum length sequence has about 500K tokens. GPU Memory is about 16 …
26.04.2019 · PyTorch’s RNN (LSTM, GRU, etc) modules are capable of working with inputs of a padded sequence type and intelligently ignore the zero paddings in the sequence. If the goal is to train with mini-batches, one needs to pad the sequences in each batch. In other words, given a mini-batch of size N, if the length of the largest sequence is L, one ...
Apr 14, 2018 · Yes, you code is correct and will work always for a batch size of 1. But, if you want to use a batch size other than 1, you’ll need to pack your variable size input into a sequence, and then unpack after LSTM. You can find more details in my answer to a similar question. P.S. - You should post such questions to codereview.

10.11.2021 · Hi, I am trying to train an LSTM Autoencoder and I have variable length sequences. I am feeding the sequences to the network singularly, not in batches (therefore I can’t use pack_padded_sequences). I have manually padded the sequences with 0s up to the maximum sequence length and I am feeding the padded sequences to the LSTM layer. My question here …

05.09.2018 · I want to build an LSTM model which takes a state S0 as the input and then the output is a sequence of S1, S2, … Sn. The length of the output sequence is variable. Three more points: 1- Each state in the sequence depends on the previous one. So, let’s say S1 leads to S2, then S2 leads to S3 and at some point, it should be a possibility to make a decision to stop for …
