MemoryFormat

Tensor is or will be allocated in dense non-overlapping memory. Strides represented by values in strides[0] > strides[2] > strides[3] > strides[1] == 1 aka NHWC order.

Tensor is or will be allocated in dense non-overlapping memory. Strides represented by values in decreasing order.

Used in functions like clone to preserve the memory format of the input tensor. If input tensor is allocated in dense non-overlapping memory, the output tensor strides will be copied from the input. Otherwise output strides will follow torch.contiguous_format
