Hello, i'am currently blocked with this message error, can u help me guys plz, this is my code :

chemin_image = "/home/TNguyen2/Documents/FLAIR/img/927491-2000_6302587-2000_50.tif"
chemin_msk = "/home/TNguyen2/Documents/FLAIR/msk/927491-2000_6302587-2000_50.tif"
image = tiff.imread(chemin_image, 0)
msk = tiff.imread(chemin_msk, 0)

Vérifier les tailles des images

if image.shape[:2] != msk.shape[:2]:
raise ValueError("Les tailles des images ne correspondent pas.")

height, width = image.shape[:2]

crop_image = image[:height, :width]
crop_msk = msk[:height, :width]
msk_reduced = msk[:, :, :4]
img_reduced = image[:, :, :4]
image_gris = np.mean(image, axis=2).astype(np.uint8)

Convertir le masque en image binaire

masque_binaire = cv2.cvtColor(msk_reduced, cv2.COLOR_BGR2GRAY)
_, masque_binaire = cv2.threshold(masque_binaire, 127, 255, cv2.THRESH_BINARY)

Appliquer le masque à l'image en utilisant le masque binaire

superposition = cv2.bitwise_and(image_gris, image_gris, mask=masque_binaire)

resized_image = cv2.resize(crop_image, (crop_msk.shape[1], crop_msk.shape[0]))
resized_msk = cv2.resize(crop_msk, (crop_image.shape[1], crop_image.shape[0]))
superposition = cv2.addWeighted(resized_image, 0.3, crop_msk, 0.7, 0)

Afficher la superposition

cv2.imshow("Image", resized_image)
cv2.imshow("Mask", crop_msk)
cv2.waitKey(0)
cv2.destroyAllWindows()
