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

TensorBoard 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)

  appear when TensorBoard is launched programmatically via Python (#3695)
• Fixed download links in Custom Scalars (#3794)

  @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).

    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)
• The tensorboard dev list subcommand now reports the total size of stored
  binary objects (e.g., graphs) for each experiment (#3464)
