Hi, can you help with the traceback error at the end.

{moderator edit - solution code removed}

This is a 3 by 3 by 2 array, typically images will be (num_px_x, num_px_y,3) where 3 represents the RGB values

t_image = np.array([[[ 0.67826139, 0.29380381],
[ 0.90714982, 0.52835647],
[ 0.4215251 , 0.45017551]],
​
[[ 0.92814219, 0.96677647],
[ 0.85304703, 0.52351845],
[ 0.19981397, 0.27417313]],
​
[[ 0.60659855, 0.00533165],
[ 0.10820313, 0.49978937],
[ 0.34144279, 0.94630077]]])

print ("image2vector(image) = " + str(image2vector(t_image)))

image2vector_test(image2vector)

That means you have not run the previous cells in the notebook since the last time you closed and reopened it. Try “Cell → Run All Above” and then run the test again.
