TensorBoard 1.5.0

The 1.5 minor series tracks TensorFlow 1.5. Note that version numbers jump from 0.4.0 to 1.5.0 to catch up with TensorFlow's version numbers, and should stay in sync from now on.

Highlights

• New Custom Scalars dashboard, which can display configurable custom line and
  margin charts based on the same data as the regular Scalars dashboard. See
  for details: https://github.com/tensorflow/tensorboard/tree/1.5/tensorboard/plugins/custom_scalar
• Many projector plugin enhancements thanks to @francoisluus, which enable
  cognitive-assisted labeling via semi-supervised t-SNE
  • t-SNE specific features: semi-supervision (#811) plus perturb (#705) and
    pause/resume (#691) buttons
  • general features: metadata editor (#753), selection edit mode (#697), edit
    box for neighbors slider (#733), 2D sprite element zooming (#696)

Features

• Image dashboard brightness and constrast sliders (#771) - thanks @edmundtong
• Top-level dashboard tabs now scroll when there are too many to fit (#730)
• Settable browser window title with --window_title flag (#804) - thanks @tkunic
• Tag filters are now reflected in the URL, making them saveable (#787)
• Pane-based dashboards now only load charts from first two panes by default,
  which should improve responsiveness (#643 defaults tag filter search string
  to empty, and #871 makes first two panes open by default)
• Lower latency to serve TensorBoard HTML thanks to preloading in memory (#708)
• Lazy imports ("import tensorboard as tb") now work for summary APIs (#778)
• PR curve summaries now have pb (#633) and raw_data_pb (#646) versions

Bug fixes

• #265 - fixed --logdir to handle Windows drive letters - thanks @shakedel
• #784 - fixed bug in find similar subgraph algo - thanks @trisolaran
• Graph plugin fixed to
  • correctly render function nodes (#817)
  • pan to nodes more reliably (#824, #837)
  • rebuild hierarchy if callbacks change to avoid race in rendering (#879)
