mediapipe hangs in google cloud functions.

[nakamura-alice]

I am trying to use the mediapipe package in the python runtime of cloud function's gen1. However, when I execute a function from the mediapipe package, the process hangs there. The process does not stop and there is no error message. I have debugged with the print function in the cloud functions and confirmed that the mediapipe package is imported. I have also set the memory to 8,192MB and the timeout to 5 minutes, but the situation remains the same.

Do you know the reason and how to run mediapipe in cloud functions?

code

import mediapipe as mp
import cv2
import numpy as np

class FaceService:
    mpFaceMesh = mp.solutions.face_mesh
    faceMesh = mpFaceMesh.FaceMesh(max_num_faces=2, static_image_mode=True)
    mpDraw = mp.solutions.drawing_utils
    drawSpec = mpDraw.DrawingSpec(thickness=1, circle_radius=2)

    def get_landmarks468(self, img):
        imgRGB = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
        selfFaceMesh = self.faceMesh
        results = selfFaceMesh.process(imgRGB)   <- it hangs here
        faceLms = results.multi_face_landmarks[0]
        ih, iw, ic = img.shape
        return np.matrix([[int(lm.x*iw), int(lm.y*ih)] for lm in faceLms.landmark])

def hello_world(request):
    face_service = FaceService()
    image = cv2.imread("path/to/test/image")
    landmark = face_service.get_landmarks468(image)
    print(landmark)

if __name__ == "__main__":
    hello_world(None)
