使用 colab 训练图像分类模型

Question

我按照模板更改链接，但它不起作用 https://colab.research.google.com/github/tensorflow/tensorflow/blob/master/tensorflow/lite/g3doc/tutorials/model_maker_image_classification.ipynb#scrollTo=3jz5x0JoskPv

这是我的数据集 https://firebasestorage.googleapis.com/v0/b/lol-fypproject.appspot.com/o/lol.tgz?alt=media&token=d07b81bd-442f-4ebe-920e-3772598fbb20

原代码

image_path = tf.keras.utils.get_file(
  'flower_photos.tgz',
  'https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz',
  extract=True)
 image_path = os.path.join(os.path.dirname(image_path), 'flower_photos')

我改变了

image_path = tf.keras.utils.get_file(
  'lol.tgz',
  'https://firebasestorage.googleapis.com/v0/b/lol-fypproject.appspot.com/o/lol.tgz?alt=media&token=d07b81bd-442f-4ebe-920e-3772598fbb20',
  extract=True)
image_path = os.path.join(os.path.dirname(image_path), 'lol')

行错误并显示错误信息

data = ImageClassifierDataLoader.from_folder(image_path)

---------------------------------------------------------------------------

----> 1 data = ImageClassifierDataLoader.from_folder(image_path)
  2 train_data, test_data = data.split(0.9)

 in 
 from_folder(cls, filename, shuffle)
 69     all_image_size = len(all_image_paths)
 70     if all_image_size == 0:
 ---> 71       raise ValueError('Image size is zero')
 72 
 73     if shuffle:

 ValueError: Image size is zero
