keras version to use with tensorflow-gpu 1.4

Question

I am using ubuntu 16, with python 3, tf-GPU with keras.

I downgraded to tf 1.4 due to cuda errors as explained here

But now I am getting this error

TypeError: softmax() got an unexpected keyword argument 'axis'

Seems that this is an API change in tensorflow and new keras is not suitable for the old tf.

I can't find what is the correct keras version to use with tf 1.4 gpu. What is the correct one?

Answer 1

Keras - Tensorflow versions compatibility is a frequent problem that i have faced many times myself. I am keeping in my bookmarks this compatibility table, with matches of tensorflow and keras versions. It would seem that keras 2.0.8 is compatible with tensorflow 1.4.

Answer 2

If you are using keras exclusively with the tensorflow backend, I would recommend to use the keras implementation found in tf.keras rather than the keras module. That way, you won't scratch your head about possible incompatibilities or bugs (see also that question).
