Release 0.1.2 : PyTantale

🚀 Features

  • (pytantale) Added the python module. Allowing optimizing Python functions with Python Outcome (PyOutcome) and Python FuncState (PyState).
  • (pyhpo!) Added the pyhpo! procedural macro. Similar to hpo!, but for Python integration.
  • (Runable) Added the extract method to the [Runable] trait to retrieve components of an experiment.
  • (tantale) Added the py feature, allowing to activate or not Python function handling with pyo3.
  • (hpo!) The macro now creates an indices submodule within the user-defined searchspace module. It contains internal index within searchspace as constants with UPPERCASE variable name.
  • (HasId) The HasId trait now implements ref_id and mut_ref_id methods, allowing to borrow and mutably borrow an Id.
  • (HasStepId) [breaking] Added the HasStepId describing objects containing a StepId. Modified all multi-fidelity runs and evaluators to further constrain solutions and shapes to implement HasStepId.
  • (run/load) The constructor functions mono, threaded, distributed and related functions are now generic over Id. Same for the load! macro.
  • (StepId) Added the StepId trait describing an Id able to track how many times a function was partially evaluated by a stepped function.
  • (StepSId) Added the StepSId struct implementing StepId, and used within multi-fidelity-related objects.
  • (Bool) Added From<Grid>.
  • (Bounded) Added From<Mixed> for Real, Nat, Int, Unit.
  • (GridDom) Added From<Mixed> for GridReal, GridNat, GridInt.
  • (Unit) Added From<Mixed>.
  • (macros) Added the mpi and py features to the macros crate.
  • (MessagePack) All unwraps for functions returning Results<_,CheckPointError> are replaced by a map_err to CheckpointError.
  • (experiment) Added type alias ExpComponent.
  • (Objective/Stepped) Objective and Stepped now implement Clone

🐛 Bug Fixes

  • (asha) At initialization, if the only budget is the minimum one, then consider minimum and maximum budgets [bmin,bmax] .
  • (asha) Solved an issue when k==0, the current budget, was not reset to bmin.
  • (hyperband) Now the first_step method initializes the inner batch optimizer's batch size.
  • (sha) Now SHA builds a vec of all available budgets. Preventing the case where only a minimum budget is computable and replaced with bmax instead of considering [bmin, bmax].
  • (GridDomDistribution) [breaking] Modified generic T bounds from BoundedBounds to GridBounds.
  • (Outcome) [breaking] The Outcome derive macro does not handle generics anymore. This simplifies Python integration.
  • (FolderConfig) [breaking] The given path is now transformed with std::path::absolute to get the absolute path even if it does not exist. Path existence is checked later.
  • (StepId) [breaking] Replaced SId by StepSId for all Fidelity-based experiments. This allows linking by id and id_step recorded solutions.
  • (mpi_run) [breaking] Resolved an issue when loading an MPI-distributed experiment Objective. The master process was stuck due to an extra barrier.
  • (mpi_run) [breaking] Resolved an issue during draining and reinjection of overflowing solutions when an MPI-distributed Stepped experiment was ending.
  • (mpi_run) Solved an issue when filling workers. If no solution could be sent to the first idle worker, then the filling phase was terminated. No solution was evaluated, even if it could have been sent to another idle worker.
  • (mpi_run) Solutions are now correctly discarded.

🚜 Refactor

  • (tests) Added a cleaner module, containing the tmp folder cleaner + Python tests.

📚 Documentation

  • (pytantale) Added a Pytorch $\times$ Tantale tutorial
  • (GridDom) Added documentation for GridReal, GridInt, and GridNat.
  • (tantalexburn) Solved minor mistake.
  • (lib) Solved list issue.
  • (tutorial) Update multi-objective optimizer tutorials with StepSId.
  • (hyperband) Rewrote pseudo code.

🧪 Testing

  • (reader) Now all experiment outputs are verified using the same function, using the theoretical number of expected outputs. Or + an epsilon when randomness is involved.
  • (fidelity) Update all fidelity tests with StepSId.
  • (mpi) MPI test examples now cleanly remove temporary folders.
  • (mpi) Added a bash script to run mpi_*.rs tests sequentially.
  • (pytantale) Added test for mono, threaded, and distributed for Objective and Stepped cases with Python functions.
