What is right batch normalization function in Tensorflow?

Question

In tensorflow 1.4, I found two functions that do batch normalization and they look same:

1. tf.layers.batch_normalization (link)
2. tf.co

Answer 1

As show in doc, tf.contrib is a contribution module containing volatile or experimental code. When function is complete, it will be removed from this module. Now there are two, in order to be compatible with the historical version.

So, the former tf.layers.batch_normalization is recommended.
