(-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

Question

I am trying to recognize text from an image to then have the text outputted; however, this error spits out:

Traceback (most recent call last):

Answer 1

This means you are passing a Uninitialized variable to

> cv2.cvtColor()

After this statement:

# Read image with opencv
img = cv2.imread(img_path)

Can you try to print the img variable before passing to cv2.cvtColor() function

> print(img) or print(img.shape)

to make sure function call to read the image is successful
