Tensorboard

The 1.13 minor series tracks TensorFlow 1.13.

Compatibility note: As of 1.13, TensorBoard has begun transitioning its own use
of some TensorFlow APIs to align with their naming in TF 2.0, and as a result
TensorBoard 1.13+ strictly requires TensorFlow 1.13+.

Features

- What-If tool notebook mode and general improvements
- Now usable directly inside Jupyter and Colab notebooks (1662, 1745, 1788)
- Added comparison of multiple models (1589, 1672)
- Added CSV loading model (1597)
- Added global partial dependence plots (1604)
- Added custom prediction function support (1842)
- (Alpha) TensorBoard can be embedded inside Juptyer and Colab notebooks via a
`%tensorboard` magic, after loading the `tb.notebook` extension (1813, 1822)
- Profile dashboard overview page now shows step time breakdown (PR 1683)
- Line chart "log" scale is now a true log scale (1507)
- When no --port flag is specified, TensorBoard will now search for open ports
near the default port (6006) if that port is already in use (1851)
