Update to Tensorflow 2

[cossio]

On Tensorflow 2 I get some errors, e.g.:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

Please update

Hello, this is the fix I have used:
I went into the models.py and added this line to the end of the imports:

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

This should switch you back to v1.x behaviour. This is a temporary placeholder. I'll fork this sometime and write it for 2.x

Hello, I suggest using the code as follows:

import tensorflow._api.v2.compat.v1 as tf
tf.disable_v2_behavior()
