Sparse x Dense -> Dense matrix multiplication

[nitish (Nitish Gupta)]

There is already a patch for torch.mm. You can use that in the meantime. I am using it currently and it if working fine.

Does PyTorch support autograd on sparse matrix?

Hi there, I am a beginner trying to learn PyTorch and there is one question bugging me. I know PyTorch support sparse x dense -> dense function in torch.mm. However, I don’t think it currently supports autograd on sparse variables (say sparse matrix). Examples are: x = torch.sparse.FloatTensor(2,10) y = torch.FloatTensor(10, 5) sx = torch.autograd.Variable(x) sy = torch.autograd.Variable(y) torch.mm(sx, sy) # fails Errors: TypeError: Type torch.sparse.FloatTensor doesn’t implement stateless …
