Installation pip install trackio Abstract This callback enables tracking of Optuna studies in Trackio. By default, the study is tracked as a single experiment run, where all suggested hyperparameters and optimized metrics are logged and visualized as a function of optimizer steps.
Trackio is offline-first and does not require authentication for local experiment tracking. Optionally, tracked experiments can be synchronized to Hugging Face Spaces for remote visualization and sharing.
The callback also supports multi-run mode, where each Optuna trial is tracked as an independent Trackio run.
