导入错误：在Windows 7上没有名为cv2的模块

Question

我使用pip命令安装cv2，但它给出错误没有找到与cv2相匹配的 分配。 下面我为代码

import numpy as np 
import cv2 

cap = cv2.VideoCapture(0) 

while(True): 
    # Capture frame-by-frame 
    ret, frame = cap.read() 

    # Our operations on the frame come here 
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) 

    # Display the resulting frame 
    cv2.imshow('frame',gray) 
    if cv2.waitKey(1) & 0xFF == ord('q'): 
     break 

# When everything done, release the capture 
cap.release() 
cv2.destroyAllWindows() 

Answer 1

安装OpenCV或CV2使用PIP
