Methods

__init__(sess, session_root, watch_fn=None, log_usage=True)

Constructor of DumpingDebugWrapperSession.

Args:

  • sess: The TensorFlow Session object being wrapped.
  • session_root: (str) Path to the session root directory. Must be a directory that does not exist or an empty directory. If the directory does not exist, it will be created by the debugger core during debug tf.Session.run calls. As the run() calls occur, subdirectories will be added to session_root. The subdirectories' names has the following pattern: run__ E.g., run_1480734393835964_ad4c953a85444900ae79fc1b652fb324
  • watch_fn: (Callable) A Callable that can be used to define per-run debug ops and watched tensors. See the doc of NonInteractiveDebugWrapperSession.__init__() for details.
  • log_usage: (bool) whether the usage of this class is to be logged.

Raises:

ValueError: If session_root is an existing and non-empty directory or if session_root is a file.

on_run_end(request)

See doc of BaseDebugWrapperSession.on_run_end.

on_run_start(request)

See doc of BaseDebugWrapperSession.on_run_start.

on_session_init(request)

partial_run(handle, fetches, feed_dict=None)

partial_run_setup(fetches, feeds=None)

Sets up the feeds and fetches for partial runs in the session.

run(fetches, feed_dict=None, options=None, run_metadata=None)

Wrapper around Session.run() that inserts tensor watch options.

Args:

  • fetches: Same as the fetches arg to regular Session.run().
  • feed_dict: Same as the feed_dict arg to regular Session.run().
  • options: Same as the options arg to regular Session.run().
  • run_metadata: Same as the run_metadata arg to regular Session.run().

Returns:

Simply forwards the output of the wrapped Session.run() call.

Raises:

  • ValueError: On invalid OnRunStartAction value.
