Passing -1 as the size for a dimension means not changing the size of that dimension. Tensor can be also expanded …Dec 30, 2018 · expand works along singleton dimensions of the input tensor. In your example, you are trying to expand a 1-by-18 tensor along its (non-existent) third and fourth dimensions - this is why you are getting an error. The only singleton dimension (=dimension with size ==1) you have is the first dimension. I am working with an autoencoder and I use latent.view(batch_size,1,-1).expand(-1,<max_length>,-1) to add a timestep dimension and then repeat the latent space that many time steps to then feed into the decoder RNN. When I use .expand() in this way, how does the gradient backpropagate through it?
