  flags) is removed to ease maintenance (#3539)

TensorBoard 2.2.1

TensorBoard.dev updates

• TensorBoard.dev now renders model graphs, for experiments uploaded starting
  from this release.
  • The tensorboard dev upload subcommand now sends the model graph, when
    available, so that it can be rendered via the Graphs plugin on
    TensorBoard.dev.
  • Large node attribute values (which would not be rendered anyway) are
    filtered out before upload.
  • Graphs that remain larger than 10MB after filtering are not uploaded.
• The tensorboard dev upload command supports a --plugins option to
  explicitly indicate the desired plugins for which summary data should be
  uploaded (#3402, #3492)

Features

  information and usage instructions.

TensorBoard 2.0.0

The 2.0 minor series tracks TensorFlow 2.0.

Breaking changes

• TensorBoard now serves on localhost only by default to avoid unintentional
  overexposure. To expose TensorBoard to the network, either use a proxy, bind
  to a specific hostname or IP address by using the --host flag, or explicitly
  enable the previous behavior of binding on all network interfaces by passing
  the flag --bind_all. See PR #2589.

• The --logdir flag no longer supports passing multiple comma-delimited paths,
  which means that it now supports paths containing literal comma and colon
  characters, like ./logs/m=10,n=20,lr=0.001 or ./logs/run_12:30:15. To
  mimic the old behavior, prefer using a tree of symlinks as it works with more
  plugins, but as a fallback the flag --logdir_spec exposes the old behavior.
  See PR #2664.

• Projector plugin visualize_embeddings() API now takes logdir as its first
  parameter rather than writer (which only supported TF 1.x summary writers).
  For backwards compatibility TF 1.x writers will still be accepted, but passing
  the logdir explicitly is preferred since it works without any dependency on
  TF 1.x or 2.x summary writing. See PR #2665.

• The namespace tensorboard.summary.* now aliases the summary API symbols in
  tensorboard.summary.v2.* rather than those in tensorboard.summary.v1.*.
  The old symbols can still be accessed under the .v1 names. Note that the
  new v2 API symbols are exposed in TF 2.0 as the new tf.summary.* API and
  this is normally how they should be used. See PR #2670.

Features

• Smarter log directory polling can be used by passing --reload_multifile=true
  to poll all "active" event files in a directory rather than only the last one.
  This avoids problems where data written to the non-last file never appears.
  See PR #1867 for details, including how to adjust the "active" threshold.

• What-If Tool now can sort PD plots by interestingness (#2461)

TensorBoard 1.15.0

The 1.15 minor series tracks TensorFlow 1.15.

Features

• Embeddings projector now shows sprite images in the nearest neighbors list
  (#2543) - thanks @beasteers
• When recording hyperparameters, the trial ID can now be customized, for easier
  integration with existing tuner systems (#2442)
• Improvements to Colab and Jupyter notebook integration:
  • The TENSORBOARD_BINARY environment variable can now be set to invoke a
    non-default tensorboard binary (#2386)
  • Error messages are now clearer when the TensorBoard binary fails to launch
    (#2395)
  • The %tensorboard magic no longer spams log messages when a different
    version of TensorBoard is already running on the same machine (#2470)
  • The %tensorboard magic can now be used in Jupyter notebooks running on
    hosts other than localhost (#2407)
• What-If Tool improvements:
  • Errors running inference are now surfaced in the What-If Tool UI (#2414)
  • Median error stats are now displayed in addition to mean error stats (#2434)
• Mesh plugin improvements:
  • Now compatible with TensorFlow 2.0 via a new summary_v2 module (#2443)
  • The number of vertices in the mesh can now be dynamic (#2373)
• Profile dashboard improvements:
  • Wasted time now appears in the node table, and can be used as a sort key
    (#2525)
  • Memory bandwidth utilization now appears in the dashboard header (#2525)
• Improvements for plugin developers:
  • Plugins can now be rendered in an iframe whose source is served from the
    plugin backend, eliminating the need to bundle a frontend with the
    TensorBoard binary
  • Plugins can now be discovered dynamically and loaded at runtime, by defining
    a tensorboard_plugins entry point
  • See our example dynamically loaded plugin for a plugin to
    use as a starting point, plus documentation
  • TensorBoard now uses Polymer 2.7 (#2392, et al.)

Bug fixes

  failures (PR #2605)
