将下载的数据集处理成图片文件！

# 10000 个视频，每个视频20帧，每帧宽64  高64
import numpy as np
import cv2
import os

data = data.transpose(1, 0, 2, 3)
print(data.shape) # 10000,20,64,64

for index in range(len(data[:, 0, 0, 0])):

    count=0
    for j in data[index,...]:

        cv2.imwrite(filename,img)
        # cv2.imshow('img0', img)
        # cv2.waitKey(0)

处理后格式：
