将图像转换为视频时抛出内存不足错误，即使使用了大约8GB，但我有64GB

Question

尝试将图像转换为视频，但出现此错误，

  

文件“ C：/test.py”，第35行，在       convert_frames_to_video（pathIn，pathOut，fps）文件“ C：/test.py”，第17行，在convert_frames_to_video中       img = cv2.imread（文件名）   cv2.error：OpenCV（4.0.0）C：\ projects \ opencv-   python \ opencv \ modules \ core \ src \ alloc.cpp：55：   错误：（-4：内存不足）无法在以下位置分配72000000字节   函数'cv :: OutOfMemoryError'

任务管理器中使用的内存为8GB，总内存为64GB ...我正在使用PyCharm IDE运行此代码，

import cv2
import numpy as np
import os

from os.path import isfile, join

def convert_frames_to_video(pathIn, pathOut, fps):
    frame_array = []
    files = [f for f in os.listdir(pathIn) if isfile(join(pathIn, f))]

    for i in range(len(files)):
        filename = pathIn + "\\" + files[i]
        # reading each files
        img = cv2.imread(filename)
        print(filename)
        height, width, layers = img.shape
        size = (width, height)
        print(filename)
        # inserting the frames into an image array
        frame_array.append(img)

    out = cv2.VideoWriter(pathOut, cv2.VideoWriter_fourcc(*'DIVX'), fps, size)

    for i in range(len(frame_array)):
        # writing to a image array
        out.write(frame_array[i])
    out.release()

pathIn = 'C:\\Images'
pathOut = 'video.avi'
fps = 25.0
convert_frames_to_video(pathIn, pathOut, fps)
