Dataset functions are missing from documentation again

[joaquinvanschoren]

Description

When checking the docs for the OpenMLDataset object, only the constructor is documented - none of the operations:
https://openml.github.io/openml-python/develop/generated/openml.OpenMLDataset.html#openml.OpenMLDataset

E.g. dataset.get_data should be fully documented, and there are docstrings - they just don't show up in the docs:
https://github.com/openml/openml-python/blob/develop/openml/datasets/dataset.py#L653

Steps/Code to Reproduce

Check docs: https://openml.github.io/openml-python/develop/generated/openml.OpenMLDataset.html#openml.OpenMLDataset

(same problem for both master and develop)

Expected Results

Documentation on all operations.

Actual Results

Only the constructor is documented.

[PGijsbers]

Agreed, with the remark that only public methods should be included (i.e. not those that are prefixed with an underscore).

[PGijsbers]

OpenML classes derive some functionality from the OpenMLBase class, e.g. push_tag and remove_tag, publish and so on. These should also be included in the API documentation.

Fixed in #1044
