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 (...). WebMar 13, 2024 · We can access the value of a tensor by using indexing and slicing. Indexing is used to access a single value in the tensor. slicing is used to access the sequence of values in a tensor. we can modify a tensor by using the assignment operator. Assigning a new value in the tensor will modify the tensor with the new value.
