[bug#50956] [PATCH 0/3] Add Optuna.

[Vinicius Monego]

This patchset adds the Optuna hyperparameter optimization framework.

Optuna requires a number of ML frameworks for the whole test suite. I deleted 
some test files and added comments on missing packages.

I packaged Skorch in the series but it's an optional dependency that is only 
used in the integration tests, which are completely disabled. The latest 
version of scikit-optimize (0.8.1), another optional dependency, is 
incompatible with the scikit-learn version in Guix (0.24.x). I am waiting for 
the next release to package it. The other dependencies are trickier.

The executable in bin/ throws an error coming from pygobject, which I couldn't 
update. While there is a CLI, Optuna is mainly used as a library, that is why I 
prefix it with python-.

Vinicius Monego (3):
  gnu: Add python-cma.
  gnu: Add python-skorch.
  gnu: Add python-optuna.
