我怎么知道在tf.keras中实现了哪个版本的Keras API？

Question

In the standard implementation of Keras, one can get the API version using keras.__version__ .

However, there is no tf.keras.__version__ .

So how do I check the version of the Keras API implemented in tf.keras ?

Answer 1

You can simply run this code

from tensorflow.python import keras
print(keras.__version__)

which is compatible with TF v1.8.0.

Answer 2

You can retrieve the version of Keras implemented in tf.keras using

from tensorflow.python.keras._impl.keras import __version__ as tf_keras_version
print(tf_keras_version)
# 2.1.5-tf (in TF 1.8)

It seems that from TF 1.9 on, it will actually be accessible as tf.keras.__version__ , as it should.

Answer 3

This has recently been updated:

>>> import tensorflow as tf
>>> print(tf.keras.__version__)
2.1.6-tf
>>> print(tf.__version__)
1.12.0
