2.3.0
7c5fa38

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)

Bug fixes

  • Projector plugin
    • Shows data when logs exist in both logdir root and subdirectory (#3694)
    • Fixed incorrect embeddings from TF2 checkpoints (#3679)
    • Added support for binary format, with 2x speedup loading large tensors in
      some cases (#3685) - thanks @RustingSword
    • Added Colab tutorial for Projector plugin (#3423)
  • Notebooks
    • Increased port scanning from 10 to 100 to better support multi-tenant
      Notebooks (#3780) - thanks @jerrylian-db
    • Add proxy (e.g. jupyter-server-proxy) support for %tensorboard magics
      (#3674) - thanks @zac-hopkinson
      • Set the TENSORBOARD_PROXY_URL environment variable
        export TENSORBOARD_PROXY_URL="/proxy/%PORT%/"
  • Dynamic plugins (Projector, Fairness Indicators, Profiler, What-If Tool)
    appear when TensorBoard is launched programmatically via Python (#3695)
  • Fixed download links in Custom Scalars (#3794)
  • Updated broken docs (#3440, #3459, #3561, #3681) - thanks @LexusH,
    @ManishAradwad, @ricmatsui, @robertlugg
  • Better handling of S3-related InvalidRange errors (#3609) - thanks @ahirner
  • Fixed deprecated numpy usage (#3768) - thanks @lgeiger

Deprecations

  • Beholder will be removed in a future release (#3843)
  • Debugger (V1) will be removed in a future release, in favor of the
    aforementioned V2 version

Misc

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).
