Steps per second monitor.

## Methods

### after_create_session(session, coord)

Called when new TensorFlow session is created.

This is called to signal the hooks that a new session has been created. This has two essential differences with the situation in which begin is called:

• When this is called, the graph is finalized and ops can no longer be added to the graph.
• This method will also be called as a result of recovering a wrapped session, not only at the beginning of the overall session.

#### Args:

• session: A TensorFlow Session that has been created.
• coord: A Coordinator object which keeps track of all threads.

### end(session)

Called at the end of session.

The session argument can be used in case the hook wants to run final ops, such as saving a last checkpoint.

#### Args:

• session: A TensorFlow Session that will be soon closed.
