Someone replied to me in an old comment that for fast Python you have to use numpy. In the folder there is a program in plain python, another with numpy and another with numba. I'm not sure why only one is shown in the data.

Disclaimer: I used numpy and numba, but my level is quite low. Almost as if I just type `import numpy as np` and hope the best.

For what it's worth, I've ported a lot of heavily optimized numpy code to Julia for work, and consistently gotten 10x-100x speedups, largely due to how much easier it is to control memory allocations and parallelize more effectively.

As do we all. If you browse through deep learning code a large majority is tensor juggling.
