optuna.visualization

The :mod:~optuna.visualization module provides utility functions for plotting the optimization process using plotly and matplotlib. Plotting functions generally take a :class:~optuna.study.Study object and optional parameters are passed as a list to the params argument.

.. note:: In the :mod:optuna.visualization module, the following functions use plotly to create figures, but JupyterLab_ cannot render them by default. Please follow this installation guide_ to show figures in JupyterLab_. .. note:: The :func:~optuna.visualization.plot_param_importances requires the Python package of scikit-learn <https://github.com/scikit-learn/scikit-learn>__.
