Efficient PyTorch: Tensor Memory Format Matters

WebPyTorch allows a tensor to be a View of an existing tensor. View tensor shares the same underlying data with its base tensor. Supporting View avoids explicit data copy, thus allows us to do fast and memory efficient reshaping, slicing and element-wise operations. For example, to get a view of an existing tensor t, you can call t.view (...).
