我按照模板修改了链接，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

原始代码

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')

我修改为

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')

这行代码出错了，错误信息如下

data = ImageClassifierDataLoader.from_folder(image_path)---------------------------------------------------------------------------ValueError                                Traceback (most recent call last)<ipython-input-15-a5e7646aca55> in <module>()----> 1 data = ImageClassifierDataLoader.from_folder(image_path)  2 train_data, test_data = data.split(0.9)/usr/local/lib/python3.7/dist- packages/tensorflow_examples/lite/model_maker/core/data_util/image_dataloader.py  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

回答：

我已经找到了问题所在
