Running with Optuna's Docker images?

You can use our docker images with the tag ending with -dev to run most of the examples. For example, you can run PyTorch Simple via docker run --rm -v $(pwd):/prj -w /prj optuna/optuna:py3.7-dev python pytorch/pytorch_simple.py. Also, you can try our visualization example in Jupyter Notebook by opening localhost:8888 in your browser after executing this:

docker run -p 8888:8888 --rm optuna/optuna:py3.7-dev jupyter notebook --allow-root --no-browser --port 8888 --ip 0.0.0.0 --NotebookApp.token='' --NotebookApp.password=''
