在训练和测试数据集中加载图像时获得权限被拒绝

Question

我正在尝试在x_train中加载图像，但是却出现了一个没有此权限的错误。

import keras
import tensorflow as tf

train_path = open('C:/Users/dwika/Desktop/catdog/data/train', 'rb')
x_train = []
test_path = open('C:/Users/dwika/Desktop/catdog/data/test', 'rb')
x_test = []

for img in train_path:
    img_path = train_path + img
    x = keras.preprocessing.image.load_img(img_path)
    x_train.append(x)

for img in test_path:
    img_path = test_path + img
    x = keras.preprocessing.image.load_img(img_path)
    x_test.append(x)

我遇到这种错误。

 Using TensorFlow backend.
