Display NumPy array as continuously updating image with Glumpy

Question

I\'ve got a simulation model running in Python using NumPy and SciPy and it produces a 2D NumPy array as the output each iteration. I\'ve been displaying this output as an image

Using pyformulas 0.2.8 you can use pf.screen to create a non-blocking screen:

import pyformulas as pf
import numpy as np

canvas = np.floor(np.random.normal(scale=50, size=(480,640,3)) % 256).astype(np.uint8)
screen = pf.screen(canvas)

while screen.exists():
    canvas = np.floor(np.random.normal(scale=50, size=(480,640,3)) % 256).astype(np.uint8)
    screen.update(canvas)

#screen.close()
