Question

我无法从TensorFlow Hub导入elmo模块。我能够导入其他模块并成功使用它们。我在具有GPU的GCP Jupyterlab实例上运行TF2.0。当我尝试这个：

import tensorflow as tf
import tensorflow_hub as hub

elmo = hub.Module("https://tfhub.dev/google/elmo/3", trainable=True)

我得到：

hub.Module API在“急切”模式下不起作用。请签出https://www.tensorflow.org/hub/migration_tf2，并注意文件格式从TF1 hub.Module更改为TF2 SavedModel。

尝试从TensorFlow Hub导入Elmo模块时出现错误？
