optuna.visualizationΒΆ
The visualization
module provides utility functions for plotting the optimization process using plotly and matplotlib. Plotting functions take generally take a Study
object and optional parameters passed as a list to a params
argument.
Note
In the 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.
Plot the parameter relationship as contour plot in a study. |
|
Plot the objective value EDF (empirical distribution function) of a study. |
|
Plot intermediate values of all trials in a study. |
|
Plot optimization history of all trials in a study. |
|
Plot the high-dimentional parameter relationships in a study. |
|
Plot hyperparameter importances. |
|
Plot the parameter relationship as slice plot in a study. |
|
Returns whether visualization with plotly is available or not. |
Note
The following optuna.visualization.matplotlib
module uses Matplotlib as a backend.
