Почему я получаю сообщение об ошибке невозможности импорта при импорте функции? [закрыто] ⇐ Python

Функция, которую я пытался импортировать:

Код: Выделить всё

def findClickPositions(needle_img_path, haystack_img, threshold=0.5, debug_mode=None):

# https://docs.opencv.org/4.2.0/d4/da8/group__imgcodecs.html
needle_img = cv.imread(needle_img_path, cv.IMREAD_UNCHANGED)
# Save the dimensions of the needle image
needle_w = needle_img.shape[1]
needle_h = needle_img.shape[0]

# There are 6 methods to choose from:
# TM_CCOEFF, TM_CCOEFF_NORMED, TM_CCORR, TM_CCORR_NORMED, TM_SQDIFF, TM_SQDIFF_NORMED
method = cv.TM_CCOEFF_NORMED
result = cv.matchTemplate(haystack_img, needle_img, method)

# Get the all the positions from the match result that exceed our threshold
locations = np.where(result >= threshold)
locations = list(zip(*locations[::-1]))
#print(locations)

# You'll notice a lot of overlapping rectangles get drawn. We can eliminate those redundant
# locations by using groupRectangles().
# First we need to create the list of [x, y, w, h] rectangles
rectangles = []
for loc in locations:
rect = [int(loc[0]), int(loc[1]), needle_w, needle_h]
# Add every box to the list twice in order to retain single (non-overlapping) boxes
rectangles.append(rect)
rectangles.append(rect)
# Apply group rectangles.
# The groupThreshold parameter should usually be 1. If you put it at 0 then no grouping is
# done. If you put it at 2 then an object needs at least 3 overlapping rectangles to appear
# in the result. I've set eps to 0.5, which is:
# "Relative difference between sides of the rectangles to merge them into a group."
rectangles, weights = cv.groupRectangles(rectangles, groupThreshold=1, eps=0.5)
#print(rectangles)

points = []
if len(rectangles):
#print('Found needle.')

line_color = (0, 255, 0)
line_type = cv.LINE_4
marker_color = (255, 0, 255)
marker_type = cv.MARKER_CROSS

# Loop over all the rectangles
for (x, y, w, h) in rectangles:

# Determine the center position
center_x = x + int(w/2)
center_y = y + int(h/2)
# Save the points
points.append((center_x, center_y))

if debug_mode == 'rectangles':
# Determine the box position
top_left = (x, y)
bottom_right = (x + w, y + h)
# Draw the box
cv.rectangle(haystack_img, top_left, bottom_right, color=line_color,
lineType=line_type, thickness=2)
elif debug_mode == 'points':
# Draw the center point
cv.drawMarker(haystack_img, (center_x, center_y),
color=marker_color, markerType=marker_type,
markerSize=40, thickness=2)

if debug_mode:
cv.imshow('Matches', haystack_img)
#cv.waitKey()
#cv.imwrite('result_click_point.jpg', haystack_img)

return points

Я понятия не имею, в чем может быть проблема, я знаю, что IDE может получить доступ к этой функции, потому что она показывает мне предварительный просмотр, когда я навожу курсор мыши на «findClickPosition» в моем вызове импорта. И мой main.py, и Visions.py находятся в одном каталоге. Как я могу получить доступ к этой функции?
