Valueerror: Argument muss ein dichtes Tensor sein - Python und TensorFlow

Question

ich einige Teile meines Codes zu extrahieren, die auf die Frage von Bedeutung sein könnten Ich habe:

from PIL import Image 
import tensorflow as tf 

data = Image.open('1-enhanced.png') 
... 
... 
raw_data = data 
raw_img = raw_data 

Ich erhalte die folgende lange Nachricht, die ich nicht sicher bin, wie zu analysieren (Sie haben keine Ahnung, was vor sich geht hier):

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

einfach den Kommentar verfasst, da sie das Problem gelöst zu haben scheint:

Versuchen Sie es zu einem numpy Array konvertieren:

numpy.asarray(Image.open('1-enhanced.png').convert('L'))
