Я собираюсь написать скрипт Python для загрузки изображений из каталога и изменения их размера, поэтому при загрузке изображений из каталога я получаю эту ошибку. 

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)

Здесь я получилошибка "OSError: [Errno 24] Слишком много открытых файлов: '/home/thisuri/Documents/Re-Train_OCR/Inputs/00009690_B543XY65.png'"

Ниже приведена трассировка назад;

Как это решить?

Вам нужно закрыть файлы после их открытия.Попробуйте эту версию: 

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
...
