Basic loop to train a model.

    supervisor, train_step_fn, args=None, kwargs=None, master=''

Calls train_step_fn in a loop to train a model. The function is called as:

train_step_fn(session, *args, **kwargs)

It is passed a tf.compat.v1.Session in addition to args and kwargs. The function typically runs one training step in the session.


  • supervisor: tf.compat.v1.train.Supervisor to run the training services.
  • train_step_fn: Callable to execute one training step. Called repeatedly as train_step_fn(session, *args **kwargs).
  • args: Optional positional arguments passed to train_step_fn.
  • kwargs: Optional keyword arguments passed to train_step_fn.
  • master: Master to use to create the training session. Defaults to "" which causes the session to be created in the local process.
