Question

我正在尝试使用Google Colab在CIFAR上训练CNN。出现以下错误：

OSError                                   Traceback (most recent call last)
    <ipython-input-5-d55609bb9b39> in <module>()
    ----> 1 images, labels = dataset_preprocessing('/content/gdrive/My Drive/Data/cifar/train', '/content/gdrive/My Drive/Data/cifar/labels.txt', (32,32),'/content/gdrive/My Driv\]\/training_image_pickle')

    <ipython-input-4-79e4d13e78a2> in dataset_preprocessing(dataset_path, labels_file_path, image_size, image_paths_pickle)
         14     image_paths = []
         15 
    ---> 16     for image_name in os.listdir(dataset_path):
         17         try:
         18             image_path =  os.path.join(dataset_path, image_name)

    OSError: [Errno 5] Input/output error: '/content/gdrive/Data/cifar/train'

下面是dataset_preprocessing函数：

def dataset_preprocessing(dataset_path, labels_file_path, image_size, image_paths_pickle):
    '''
    Load Images and labels from dataset folder.

    :param dataset_path:String, path to the train/test dataset folder
    :param image_size: Tuple, single image size
    :param image_path_pickle: String, name of a pickle file whre all imag paths will be saved
    '''
    with open(labels_file_path, 'r') as f:
        classes = f.read().split('\n')[:-1]

    images = []
    labels = []
    image_paths = []

    for image_name in os.listdir(dataset_path):
        try:
            image_path =  os.path.join(dataset_path, image_name)
            images.append(image_loader(image_path, image_size))
            image_paths.append(image_path)
            for idx in range(len(classes)):
                if classes[idx] in image_name:  #Example: 0_frog.png
                    labels.append(idx)          
        except:
            pass
    with open(image_paths_pickle + '.pickle','wb') as f:
        pickle.dump(image_paths, f)

    assert len(images) == len(labels)
    return np.array(images), np.array(labels)

最后，我使用了Colab文档中的以下代码来安装驱动器：

from google.colab import drive
drive.mount('/content/gdrive')

在Google colab上安装Drive时出错
