Initializes summary writing for graph execution mode.

    graph=None, session=None

This operation is a no-op when executing eagerly.

This helper method provides a higher-level alternative to using tf.contrib.summary.summary_writer_initializer_op and tf.contrib.summary.graph.

Most users will also want to call tf.compat.v1.train.create_global_step which can happen before or after this function is called.



  • RuntimeError: If the current thread has no default tf.contrib.summary.SummaryWriter.
  • ValueError: If session wasn't passed and no default session.
