e.g. torch.Tensor(3,4), I will get a matrix with shape of 3,4, and I notice that the mean of this matrix is 0, but the what is the specific initialization of this operation?
I would recommend to stick to the factory methods, e.g.
torch.tensor([1, 2, 3]) etc.
torch.Tensor will return an uninitialized
FloatTensor, which might be dangerous.
