Hi all, I am recently trying to build a RNN model for some NLP task, during which I found that the RNN layer interface provided by pytorch (no matter what cell type, gru or lstm) doesn’t support masking the inputs. Masking is broadly used in NLP domain for the inputs within a single batch having different length (as inputs are generally bunch of natural language sentences), so just wondering ...

If a torch.nn.utils.rnn.PackedSequence has been given as the input, the output will also be a packed sequence. For the unpacked case, the directions can be separated using output.view (seq_len, batch, num_directions, hidden_size), with forward and backward being direction 0 and 1 respectively.
Nowadays nearly all of my code is written using Python, NumPy, and PyTorch. I moved to PyTorch from TensorFlow in 2017, and my experience has resembled Andrej Karpathy's:). I've made small open-source contributions (code, tests, and/or docs) to TensorFlow, PyTorch, Edward, Pyro, and other projects. Some of my projects can be found here: GitHub

Recurrent Neural Networks (RNNs) help us tackle sequential information like natural language. If we are going to predict properties of the current word, we better remember the words before it too. An RNN has such an internal state/memory which stores the summary of the sequence it has seen so far.

PhD Student at Edinburgh Centre for Robotics busy trying to teach machines how to learn language through natural language interaction in multi-modal environments.
PyTorch's CrossEntropyLoss already takes logits (output of last layer without activation like softmax) and returns loss value for each example. I would advise this approach as it's numerically stable (and I like it as the most minimal one). I am trying to fill in the blank using a bidirectional RNN and pytorch

Here’s the Jupyter notebook with the code: char-rnn in PyTorch.ipynb. If you click “Open in Colab” at the top, you can open it in Google’s Colab service where at least right now you can get a free GPU to do training on. The whole thing is maybe 75 lines of code, which I’ll attempt to somewhat explain in this blog post.
output (seq_len, batch, hidden_size * num_directions): tensor containing the output features (h_t) from the last layer of the RNN, for each t. So there will be hidden_size * num_directions outputs. You didn't initialise the RNN to be bidirectional so num_directions is 1. So output_size = hidden_size.
