When i run this code in jupyter notebook, I want to show some pictures of my datasets:

image.png1443×726 33.4 KB

and the output is:

image.jpg1341×731 259 KB

Two questions:
(1) The original picture is RGB, but the output looks like gary-image:confused:  Why？
(2) There is no loop in the output, but why every pitctures output nine times, and it seems output three times in every channel? Why?
Thank you~
