導入錯誤：在Windows 7上沒有名爲cv2的模塊

Question

我使用pip命令安裝cv2，但它給出錯誤沒有找到與cv2相匹配的 分配。 下面我爲代碼

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

安裝OpenCV或CV2使用PIP
