Answers for "(-215:Assertion failed) isMap() in function 'cv::FileNode::operator []'"

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

This error happened because the image didn't load properly.
So you have a problem with the previous line cv2.imread my suggestion is :

Check if the images exist in the path you give

Check the count variable to see if it has a valid number

(-215:Assertion failed) img.type() == CV_8UC1 in func

img_blur = cv2.medianBlur(self.cropped_img,5).astype('uint8')
img_thresh_Gaussian = cv2.adaptiveThreshold(img_blur, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 11, 2)
