Python Error Traceback (most recent call last):-CodePudding

I am trying the build a hand tracker in python.

there is my code

import cv2
from cvzone.HandTrackingModule import HandDetector

cap = cv2.VideoCapture(0)
detector = HandDetector(detectionCon=0.8, maxHands=1)

while True:
    success, img = cap.read()
    hands, img = detector.findHands(img, flipType=True)

    cv2.imshow("image", img)
    cv2.waitKey(1)

but I get this error

ModuleNotFoundError: No module named 'mediapipe'

CodePudding user response：

You should probably install mediapipe in your venv.

activate your venv, then try to install mediapipe :

pip install mediapipe

CodePudding user response：

the setup file setup.py in cvzone repo doesn't install the requirements , so you have to do it manually

download this requirements.txt file and do the following

cd [path]  
pip install - r requirements.txt
