optuna-dashboard

Real-time dashboard for Optuna. Code files were originally taken from Goptuna.

Getting Started

You can install optuna-dashboard via PyPI or Anaconda Cloud.

# PyPI
$ pip install optuna-dashboard

# Anaconda Cloud
$ conda install -c conda-forge optuna-dashboard

Then please execute optuna-dashboard command with Optuna storage URL.

$ optuna-dashboard sqlite:///db.sqlite3
Bottle v0.12.18 server starting up (using WSGIRefServer())...
Listening on http://localhost:8080/
Hit Ctrl-C to quit.

Note that optuna-dashboard uses wsgiref module by default. Although it requires no additional dependencies, it is NOT suitable for the production use. You can use Gunicorn via "--server gunicorn" option.

$ pip install gunicorn
$ optuna-dashboard sqlite:///db.sqlite3 --server gunicorn

More command line options

$ optuna-dashboard -h
usage: optuna-dashboard [-h] [--port PORT] [--host HOST] [--version] [--quiet] storage

Python Interface

run_server(storage: Union[str, BaseStorage], host: str = 'localhost', port: int = 8080) -> None

Start running optuna-dashboard and blocks until the server terminates. This function uses wsgiref module which is not intended for the production use.

wsgi(storage: Union[str, BaseStorage]) -> WSGIApplication

This function exposes WSGI interface for people who want to run on the production-class WSGI servers like Gunicorn or uWSGI.

Using an official Docker image

You can also use an official Docker image instead of setting up your Python environment. The Docker image only supports SQLite3, MySQL(PyMySQL), and PostgreSQL(Psycopg2).

$ docker run -it --rm -p 8080:8080 -v `pwd`:/app -w /app \
> ghcr.io/optuna/optuna-dashboard sqlite:///db.sqlite3

MySQL (PyMySQL)

$ docker run -it --rm -p 8080:8080 ghcr.io/optuna/optuna-dashboard mysql+pymysql://username:password@hostname:3306/dbname

PostgreSQL (Psycopg2)

$ docker run -it --rm -p 8080:8080 ghcr.io/optuna/optuna-dashboard postgresql+psycopg2://username:password@hostname:5432/dbname
