Wishlist: Tracking Issue

[lena-kashtelyan]

Feature requests marked as 'wishlist' will be gathered here going forward, in order to:

• improve discoverability of issues that report bugs or ask questions,
• help us easily assess these requests when roadmapping.

Please still feel free to open new issues for feature requests (or comment them here if they are short/clear), and we will take care of adding them to this post.

Status: will likely be addressed in the short-term

• Support for MOO for hierarchical search spaces without flattening the search space (Does botorch optimizer in mo setting such as qehvi, qnehvi or qnparego support hierarchical space? #1042)
• Gaussian priors for BoTorch models in Ax (How to use custom Gaussian prior for Bayesian optimization? #1647)
• Slice and contour plots for choice parameters (plot_slice with choiceParameter #1577, Plot_contour doesn't work with a Choice parameter #1624)
• Storage of Data for trials without Dataframes (associating potentially larger data, e.g. image data, with trials, and passing that data to the model directly; Question: Best way to include non-scalar types in experiment results? #880)

@lena-kashtelyan I already built a conda recipe see PR whenever we fix the windows compatibility I'll let you know.

[rpanai]

@lena-kashtelyan it is now available on conda-forge https://anaconda.org/conda-forge/ax-platform

[lena-kashtelyan]

Wow, thank you so much, @rpanai!
