Methods

__init__

__init__(
    sess,
    session_root,
    watch_fn=None,
    thread_name_filter=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.
• thread_name_filter: Regular-expression white list for threads on which the wrapper session will be active. See doc of BaseDebugWrapperSession for more 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.

partial_run

partial_run(
    handle,
    fetches,
    feed_dict=None
)

partial_run_setup

partial_run_setup(
    fetches,
    feeds=None
)

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

prepare_run_debug_urls

prepare_run_debug_urls(
    fetches,
    feed_dict
)

Implementation of abstrat method in superclass.

See doc of NonInteractiveDebugWrapperSession.prepare_run_debug_urls() for details. This implentation creates a run-specific subdirectory under self._session_root and stores information regarding run fetches and feed_dict.keys() in the subdirectory.

Args:

• fetches: Same as the fetches argument to Session.run()
• feed_dict: Same as the feed_dict argument to Session.run()

Returns:

• debug_urls: (str or list of str) file:// debug URLs to be used in this Session.run() call.

run

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.
