Does Numpy automatically detect and use GPU?

Question

I have a few basic questions about using Numpy with GPU (nvidia GTX 1080 Ti). I\'m new to GPU, and would like to make sure I\'m properly using the GPU to accelerate Numpy/Pytho

Answer 1

No. Numpy does not use GPU. But you can use CuPy. The syntax of CuPy is quite compatible with NumPy. So, to use GPU, You just need to replace the following line of your code

 import numpy as np

with

import cupy as np

That's all. Go ahead and run your code. One more thing that I think I should mention here is that to install CuPy you first need to install CUDA. Since the objective of your question is to make your computations faster by making use of GPU, I would also suggest you explore PyTorch. With PyTorch, you can do almost everything that you can do with NumPy and much more. The learning curve would also be quite smooth if you are already familiar with NumPy.
