[BUG] AttributeError: module 'tensorflow.keras.initializers' has no attribute 'truncated_normal'\n in multinomial_vae.py

[k9luo]

Description

Based on the Global Settings and Imports in the example notebook for multinomial_vae, it requires tensorflow==2.2.0-rc1 and keras==2.3.1. After I installed these two libraries and ran the code, I got AttributeError: module 'tensorflow.keras.initializers' has no attribute 'truncated_normal'\n when running multinomial_vae.py. According to Tensorflow 2.2 documentation, there isn't a class called truncated_normal but there is one named TruncatedNormal.

How do we replicate the issue?

Running the notebook would probably encounter this error.

Expected behavior (i.e. solution)

Change truncated_normal to TruncatedNormal in here and here should resolve this problem.
