 Codem's Pytorch2 introduces the notion of tensor. A tensor looks like 

a numpy array, but it is accessible to a GPU rather than a CPU, and

is immutable. The central processing unit does sequential computations;

a GPU, Graphical User Interface has thousands of core and computes in

parallel. NVIDIA's CUDA platform harnesses the GPU to do 

Deep Learning Tasks. PyTorch has scrores of functions that are callable on

a tensor.
