Question

我正在制作一个图像分类器，以使用Python和TensorFlow对火箭和飞机进行分类，但是我在用Pil.Image.Open加载我的训练图像文件夹时遇到了麻烦。这是我的代码：

train_data = "C:/Users/Will Downs/image_training/training_data/"
test_data = "C:/Users/Will Downs/image_training/test_data/"

def train_data_with_label():
  train_images = []
  for i in tqdm(os.listdir(train_data)):
    path = os.path.join(train_data, i)
    img = Image.open(path)
    img.thumbnail((64, 64), Image.ANTIALIAS)  # resizes image in-place
    train_images.append([np.array(img), one_hot_label(i)])
  shuffle(train_images)
  return train_images

def test_data_with_label():
  test_images = []
  for i in tqdm(os.listdir(test_data)):
    path = os.path.join(test_data, i)
    img = Image.open(path)
    img.thumbnail((64, 64), Image.ANTIALIAS)  # resizes image in-place
    test_images.append([np.array(img), one_hot_label(i)])
  shuffle(test_images)
  return test_images

这是我得到的错误：

   2771         exclusive_fp = True
   2772 

PermissionError: [Errno 13] Permission denied: 'C:/Users/Will Downs/image_training/training_data/Airplane'

关于这是什么原因或如何解决的任何建议？

问题是一个简单的文件夹格式化。我将图像基于标签放置在文件夹中，而不是集中在一起，而是根据标签命名。
