tensorflow/tensorboard 2.3.0

TensorBoard 2.3.0

on GitHub

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).
