Returns an Op that initializes a list of variables.


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.


  • var_list: List of Variable objects to initialize.
  • name: Optional name for the returned operation.


An Op that run the initializers of all the specified variables.
