Numpy without OpenBLAS for distribution #50

Closed alex-ong closed 4 years ago

alex-ong commented 4 years ago

Since we use it heavily in text recognition, we should benchmark it. numpy.diff, numpy.abs and numpy.sum are the key functions; which probably don't need BLAS

Every other usage of numpy is just for creating numpy arrays.

Based on this specification, we don't need BLAS: http://www.netlib.org/blas/#_level_1

Wheels for windows: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

I will post benchmark soon

Running digit.py: 1.18.5 with OpenBLAS -> 10000 iterations took:10.113064289093018 seconds 1.16.6+vanilla -> 10000 iterations took:9.158168315887451 seconds

So we can use vanilla for now.
