1.2.4

Breaking Changes

• helios.plugins.optuna.OptunaPlugin.enqueue_failed_trials has been removed in favour of helios.plugins.optuna.resume_study. See the notes below for the new system.

Feature Changes

• Provides full support for resuming stopped/interrupted optuna trials. The new resume_study function now correctly resumes studies by creating a new DB and copying the trials over, enqueuing any trials that are considered failures. Please see the documentation for more info.
• Adds a new function to checkpoint and restore samplers when using Optuna. This now provides full reproducibility (subject to the usual constraints from Optuna and PyTorch).
