绘制几个图中的图片列表

Question

I'v got a list with picture-path's and i want to "plot" them in several plots eg:

list = [['./path1/pic1.jpg','./path1/pic2.jpg',...],['./path2/pic1.jpg',...],[...]]

the output has to be in this eg 3 plots with the pictures from the list's

i've tried that way but it seems to be not right because i get this Error

    fig, ax = plt.subplots(len(list))
    for image in list:
        im = Image.open(image)
        ax.imshow(im)


AttributeError: 'numpy.ndarray' object has no attribute 'imshow'

I also tried im = mpimg.imread(image) which gaves me the same result and ax.imshow(image) without any "opening"

maybe someone know how do do this...

Answer 1

subplots function returns a ndarray of axes. It's length will be the same as the number of subplots you created. So you have to index it and show the image on the right one.

images = [...]
fig, axes = plt.subplots(len(images))
for i, image in enumerate(images):
    im = Image.open(image)
    axes[i].imshow(im)
