How to convert RGB matrix to Grayscale array in Python?

Question

I need an help to convert an array of rgb values (3 channels) into a single dimension grayscale array. Thank you so much.

Are you using some kind of graphics package? If so it will likely have a conversion function built in. — Mark Ransom, Sep 18 '22 at 16:00

If you are using PIL or Pillow to hold your RGB values as an image, the conversion is trivial:

gray_image = rgb_image.convert('L')
