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，但是我无法使用Pil.Image.Open加载我的训练图像文件夹。 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：

PermissionError Traceback (most recent call last)

关于这是为什么还是如何解决的任何建议？
