Converted image not displaying

[Abder-Rahman Ali]

I'm trying to convert a color image to a grayscale image, as follows:


from skimage import iofrom skimage.color import rgb2gray 
img = io.imread('baboon.png')
img_grayscale = rgb2gray(img)
io.imshow(img_grayscale)


The code works fine, but the image does not get displayed, why is that?


Thanks.
