TensorFlow 1.9.0-rc0 升级 tf.keras 至 Keras 2.1.6 API

TensorFlow 1.9.0-rc0 已发布。

该版本带来了不少改进和新特性:

  • Update tf.keras to the Keras 2.1.6 API.
  • tfe.Network is deprecated. Please inherit from tf.keras.Model.
  • Adding support of core feature columns and losses to gradient boosted trees estimators.
  • The distributions.Bijector API supports broadcasting for Bijectors with new API changes. See here for more details.
  • Layered variable names have changed in the following conditions:
    • Using tf.keras.layers with custom variable scopes.
    • Using tf.layers in a subclassed tf.keras.Model class. See here for more details

可以看到,1.9.0-rc0 已将 tf.keras 升级至 Keras 2.1.6 API,并且已弃用 tfe.Network,需要从 tf.keras.Model 进行继承。

也有一些破坏性的变更:

  • If you're opening empty variable scopes; replace variable_scope('', ...) by variable_scope(tf.get_variable_scope(), ...).
