我将编写一段Python脚本，用于从目录加载图像并调整大小。但是，当我从目录加载图像时出现了以下错误。请参考以下内容：

我要写一个Python脚本，用于从目录加载图像并调整它们的大小。然而，当我从目录加载图像时，遇到了以下错误。

from os import listdir
from PIL import Image as PImage
import split_folders
import os, os.path


def loadImages(path):
    imagesList = listdir(path)
    loadedImages = []
    for image in imagesList:
        img = PImage.open(os.path.join(path,image))
        loadedImages.append(img)
    return loadedImages

path = "./Inputs/"
imgs = loadImages(path)

for img in imgs:
    print(img)

我在这里遇到了一个错误：“OSError: [Errno 24] Too many open files: '/home/thisuri/Documents/Re-Train_OCR/Inputs/00009690_B543XY65.png'”

以下是追踪信息：

你要加载多少个文件？也许你应该分阶段进行处理（加载一些图像，处理它们，加载下一批图像，处理它们等）。文件和文件句柄/描述符通常是有限的资源。 - Some programmer dude

是的！我同意你的观点。这里我将加载 10,000 张图片。 - EverythingNeedToBeKnown

打开文件后，您需要关闭它们。尝试使用下面的版本：

def loadImages(path):
    imagesList = listdir(path)
    loadedImages = []
    for image in imagesList:
        with open(os.path.join(path, image), 'rb') as i:
            img = PImage.open(i)
            loadedImages.append(img)
    return loadedImages
