Question

I am trying to display an image in my notebook such as,

![title](img/x.png)

When I Change cell type to markdown it works but displays this

Answer 1

Here is some diagnostics you can make using Python itself

import os
filename = 'img/x.png'
print(os.path.abspath(filename))

Does this command print the expected path? If not, fix filename accordingly.

print(os.path.exists(filename))

Is this "True"? If not, check that the file exists.

For the following test you need OpenCV. If you don't have it, you need to install opencv-python , eg using pip install opencv-python .

import cv2
im = cv2.imread(filename)
print(im.shape)

This should print a tuple with elements image height, image width and number of channels (for a color image). If it doesn't, the image is most probably corrupted.

You can also display the image using matplotlib:

import matplotlib.pyplot as plt
plt.figure()
plt.imshow(im)
plt.show()

If you see wrong colors, probably matplotlib displays it uses a wrong palette or wrong channel order (RGB instead of BGR ets.) Take a look at plt.imshow help to find, how to fix it.
