The size of tensor a (4) must match the size of tensor b (2) at non-singleton dimension 0

     RuntimeError: The size of tensor a (4) must match the size of tensor b (2) at non-singleton dimension 0

I have this error I don't understand. In your code, dilations might increase the first dimension of the x, which is usually the batch size. Ok. However, this sometimes raise an errror on the skip connections, as in this case a vector [4, 1024, 1] is added to a vector [2, 1024, 1]. Why?

@denadai2 I met the same error, have you figured out why?
