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.
