Migrate to TF2

Caution: This API was designed for TensorFlow v1. Continue reading for details on how to migrate from this API to a native TensorFlow v2 equivalent. See the TensorFlow v1 to TensorFlow v2 migration guide for instructions on how to migrate the rest of your code.

In TF2, variables are initialized immediately when they are created. There is no longer a need to run variable initializers before using them.

Description

Used in the notebooks

Used in the tutorials
  • Tutorial on Multi Armed Bandits in TF-Agents

After you launch the graph in a session, you can run the returned Op to initialize all the variables in var_list. This Op runs all the initializers of the variables in var_list in parallel.

Calling initialize_variables() is equivalent to passing the list of initializers to Group().

If var_list is empty, however, the function still returns an Op that can be run. That Op just has no effect.

Args
var_list List of Variable objects to initialize.
name Optional name for the returned operation.
Returns
An Op that run the initializers of all the specified variables.
