hi I have written these codes about Image Processing:

homography, mask = cv2.findHomography(src_pts, dst_pts, cv2.RANSAC, 5.0)


pts = np.float32([[0, 0], [0, h - 1], [w - 1, h - 1], [w - 1, 0]]).reshape(-1, 1, 2)

dst = cv2.perspectiveTransform(pts, homography)

...

col_1 = rot_and_transl[:, 0]
col_2 = rot_and_transl[:, 1]
col_3 = rot_and_transl[:, 2]

normalise vectors

l = math.sqrt(np.linalg.norm(col_1, 2) * np.linalg.norm(col_2, 2))

but after writing "Import math" pycharm wrote some lines except Writing ERROR Clearly (i.e : typeerror or syntaxerror)

Error: failed to send plot to http://127.0.0.1:63342

Traceback (most recent call last):

result = func(*args)

Ofcourse Process finished with exit code 0

Now, I am confused about what happened in My Codes?? Do My codes Have Error? or NOT?
