问题如下 
Traceback (most recent call last): 
  File "D:/Python Charm/project/bishe/FaceDepthMeasurement.py", line 6, in <module> 
    detector = FaceMeshDetector(maxFaces=1) 
  File "D:\Python\lib\site-packages\cvzone\FaceMeshModule.py", line 32, in __init__ 
    self.faceMesh = self.mpFaceMesh.FaceMesh(static_image_mode=self.staticMode, 
  File "C:\Users\戴尔\AppData\Roaming\Python\Python38\site-packages\mediapipe\python\solutions\face_mesh.py", line 94, in __init__

FileNotFoundError: The path does not exist. 
 
代码如下- import cv2
 
 - import cvzone
 
 - from cvzone.FaceMeshModule import FaceMeshDetector
 
  
- cap = cv2.VideoCapture(0)
 
 - detector = FaceMeshDetector(maxFaces=1)
 
  
- while True:
 
 -     success, img = cap.read()
 
 -     img, faces = detector.findFaceMesh(img, draw=False)
 
  
-     if faces:
 
 -         face = faces[0]
 
 -         piontLeft = face[145]
 
  
-         cv2.circle(img,piontLeft,5,(255,0,255),cv2.FILLED)
 
  
-     cv2.imshow("Image", img)
 
 -     cv2.waitKey(1)
