OpenCV错误：错误：（215）函数cv:：cvtC中的scn==3 | | scn==4

Question

我读过很多关于包含文件完整路径的解决方案，并尝试过，但它不起作用！在

这是我工作的基本代码：

import numpy as np
import cv2
import sys
import os

# capture frames from a video
cap = cv2.VideoCapture('F:\KUNAL ECE\SPIG\ video.avi')
#cap = cv2.VideoCapture(sys.argv[1])
# Trained XML classifiers describes some features of some object we want to detect
car_cascade = cv2.CascadeClassifier('F:\KUNAL ECE\SPIG\cars.xml')

# loop runs if capturing has been initialized.
while True:
    # reads frames from a video
    ret, frames = cap.read()

    # convert to gray scale of each frames
    gray = cv2.cvtColor(frames, cv2.COLOR_BGR2GRAY)

这就是我的错误获取：-在

我认为opencv没有找到/读取您指定的avi文件。尝试删除字符串中的空格

'F:/库纳尔ECE/SPIG/视频.avi'
