list index out of range

[iliesaya]

after updating this line to make it work with openCV4 :
stitcher = cv2.createStitcher()
with
stitcher = cv2.Stitcher_create()

(venv) aya@MacBook-Pro-16 src % python myPanorama.py
len(hpair) = 3 m=1
len(hpair) = 3 m=1
len(hpair) = 0 m=-1
Traceback (most recent call last):

IndexError: list index out of range

I added this line print(f"len(hpair) = {len(Hpair)} m={m}")
just before H_im = np.linalg.inv(Hpair[m])
