Hi!
So…this might be a silly question, but where is matmul?
As can be seen from the code below from my Python interpreter,
mm works fine (as well as @, which might or might not be the same as mm or matmul , I am not sure),
but matmul doesn’t seem to exist in neither torch or a Tensor object.
What’s going on?!
>>> import torch
>>> a=torch.randn(5,6)
>>> b=torch.randn(6,7)
>>> a.mm(b)
