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

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. |
