Gpflow

A small fix for a bug in the scipy optimize wrapper.

Breaking Changes

* None

Known Caveats

* None

Major Features and Improvements

* None

Bug Fixes and Other Changes

* Patched `gpflow.optimizers.Scipy` to always assign the last good state returned by `scipy.optimize.minimize` to the model under optimization. Previously, this step could be missed if `minimize` failed in some situations, leaving the model in an arbitrary state.

The main theme of this release is documentation, with a new suite of tutorials, several upgrades to notebooks and the removal of a rather annoying bug in the documentation site.

Perhaps more notably, `check_shapes` has been removed, and can now be found [here](https://github.com/GPflow/check_shapes). This change is breaking for those who are still getting `check_shapes` from `gpflow`, although being in experimental this change does not require a new version number.

Breaking Changes

* `gpflow.experimental.check_shapes` has been removed, in favour of an independent release. Use
`pip install check_shapes` and `import check_shapes` instead.

Major Features and Improvements

* Major rework of documentation landing page and "getting started" section.

Bug Fixes and Other Changes

* Fixed bug related to `tf.saved_model` and methods wrapped in `check_shapes`.
* Documented monitoring with `Adam` optimizer.
* Fixed bug related to switching versions in documentation site
* Fixed several issues relating to mypy
