Hello everyone,

Is there any package that implements Tree-Structured Parzen Estimator (TPE) algorithm in Julia.

TPE is the same algorithm behind Optuna and Hyperopt, two of the most widely used hyperparameter tuning frameworks in Python.

That would be TreeParzen.jl, in the registry but in beta release
