python矩阵计算 gpu,Numpy是否会自动检测并使用GPU？
I have a few basic questions about using Numpy with GPU (nvidia GTX 1080 Ti). Im new to GPU, and would like to make sure Im properly using the GPU to accelerate Numpy/Python. I searched on the internet for a while, but didnt find a simple tutorial that addressed my questions. Id appreciate it if someone can give me some pointers:
1) Does Numpy/Python automatically detect the presence of GPU and utilize it to speed up matrix computation (e.g. numpy.multiply, numpy.linalg.inv, ... etc)? Or do I have code in a specific way to exploit the GPU for fast computation?
2) Can someone recommend a good tutorial/introductory material on using Numpy/Python with GPU (nvidias)?
Thanks a lot!

No.

computation?
Yes. Search for Numba, CuPy, Theano, PyTorch or PyCUDA for different paradigms for accelerating Python with GPUs.
