RuntimeWarning: überlauf aufgetreten, die in ubyte_scalars

Ich bin neu in Python und dies ist meine erste Sache, die ich habe gescriptet und ich Frage mich nur, was ich tun kann, um diese zu entfernen Warnung:

Warning (from warnings module):
  File "C:\Users\Luri\Desktop\Bot Stuff\ImageSaver.py", line 76
    currentdiff=abs(anread[w,h])-abs(bnread[w,h])
RuntimeWarning: overflow encountered in ubyte_scalars

Ich habe versucht zu Googlen, die Antwort, und nichts, war für mich klar kam, soweit dies zu beheben.

Ich versuche, ein Programm zu schreiben, dass vergleichen wird eine ständige Aktualisierung image, das von einem Rechteck um meinen cursor mit einem Referenzbild, dass ich bin auf der Suche nach.

Dann je nachdem, in welcher region sich der cursor in Bezug auf das Ziel-Bild ist, wird es entsprechend anpassen.

Danke für jede Hilfe, die Sie geben können!
