Question

我按照模板更改了链接，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')

线路错误并显示错误信息

data = ImageClassifierDataLoader.from_folder(image_path)
