python错误日志——神秘错误

python错误日志——神秘错误

        在第一次和opencv接触后，感触颇多。

        anaconda安装cv2过程坎坷，折腾了两个小时。

        最后的程序还出现了个神秘错误，不过不影响运行，本小白就写出来记录下。

        本程序作用介绍：对视频按照帧数分割成图片。

        下面是代码：

        

import cv2
import os
video_name = '02.mp4'

def save_img():
    video_path = 'C:\Users\jhon smis\Desktop\'
    videos = os.listdir(video_path)
    for video_name in videos:
        file_name = video_name.split('.')[0]
        folder_name = video_path + file_name
        os.makedirs(folder_name, exist_ok=True)
        vc = cv2.VideoCapture(video_path + '/' + video_name)
        c = 0
        rval = vc.isOpened()

        frames= 1
        count = 1

        while rval:
            c = c + 1
            rval, frame = vc.read()
            pic_path = 'G:\TUPIAN\Winter Storm Xylia Time-l-VideoIndirelim.com\'
            if rval:
                if frames%10 == 0:
                    cv2.imwrite(pic_path + str(c) + '.jpg', frame)
                    cv2.waitKey(1)
                    count += 1
                frames= frames+1
            else:
                break
        vc.release()
        print('save_success')
        print(folder_name)

程序运行时输出均正常

下面是报错

        错误表现：

        会把我桌面上的文件一个一个做出对应的空文件夹

如下图所示：

我的猜测：现在完全不确定是什么问题了，刚刚一下出现了一大堆空文件夹
