Features

  • Improved performance for scalar charts with many runs
    • Up to 50% faster network fetch times in some cases (#4050)
    • Up to 90% faster paint time in some cases (#4053)

Bug fixes

  • Docs: fixed image summary tutorial (#4206)
  • Projector Plugin: fixed bookmark loading (#4159), thanks aknoerig@!
  • Graphs: updated TPU-compatible ops list (#4024)

Deprecations

TensorBoard features that depend on TensorFlow APIs now require TensorFlow 2.x installed. Running TensorBoard 2.4.0+ with TensorFlow 1.x installed will not be supported.

Please note that this does not affect data already written to disk; summaries emitted by the TF 1.x tf.summary API are still readable and fully supported by the latest versions of TensorBoard.

Support for Python 3.5 is dropped.

Plugin dashboards have been removed:

  • Beholder: see #3843
  • Debugger V1: replaced by Debugger V2

Release 2.3.0

The 2.3 minor series tracks TensorFlow 2.3.

Features

  • The 30 sec default reload period is now customizable in the Settings UI (#2794)
  • 🧪 Experimental Debugger V2 is now available; see the tutorial on how to use the experimental TensorFlow APIs to spot NaN's in tensors, view graphs generated from executions, and the related lines in the Python source code (#3821)

TensorBoard.dev updates

  • Added support for showing the Distributions tab (#3762)
  • Uploader now displays data statistics in the console while uploading data (#3678)
  • Added new uploader command line flags (#3707)
    • --dry_run: causes the uploader to only read the logdir and display statistics (if --verbose is the default 1) without uploading any data to the server
    • --one_shot: causes the uploader to exit immediately after all existing data in the logdir are uploaded; this mode prints a warning message if the logdir doesn't contain any uploadable data
  • Upload button in the header offers a convenient, copyable command
  • 🧪 Experimental DataFrame API: You can now read Scalars data from TensorBoard.dev as a Pandas DataFrame (learn more here)

The frontend now uses Angular (replaces the Polymer entry point, which will be removed in a future release; still visible at the /legacy.html endpoint) (#3779). If you observe any bugs that do not reproduce under /legacy.html, please file an issue.

For dynamic plugins, please see their respective pages (Fairness Indicators, Profiler, What-If Tool).

    • New tensorboard dev list subcommand lists all experiments uploaded to TensorBoard.dev (#2903)
    • In the event of a transient backend issue or permanent breaking change, the uploader can now gracefully degrade and print a diagnostic (#2879)

Release 2.0.1

Features

Release 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)

Release 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

  • Scalar charts should no longer “become tiny” on certain kinds of rendering failures (PR #2605)
