LouisAmon / serialize-numpy-array.py
Last active November 16, 2017 10:03 — forked from alexland/serialize-numpy-array.py
serialize, persist, retrieve, and de-serialize a NumPy array as a binary string (any dimension, any dtype); exemplary use case: a web app calculates some result--eg, from a Machine Learning algorithm, using NumPy and the result is a NumPy array; it is efficient to just return that result to rather than persist the array then retrieve it via query
import time
import numpy
import redis
# a 2D array to serialize
A = 10 * numpy.random.randn(10000).reshape(1000, 10)
# flatten the 2D NumPy array and save it as a binary string
