How to capture image as NumPy array using PiCamera2

This will capture a raspberry pi camera image as numpy array.

The default size that will be used is 640x480px

#!/usr/bin/env python3
import time
import picamera2
import numpy as np

with picamera2.Picamera2() as camera:
    array = camera.capture_array("main")
    # TODO Do something with array
