Tutorials in the master branch are intended to work with the lastest stable version of H2O.

Tutorial versions in named branches are snapshotted for specific events. Scripts should work unchanged for the version of H2O used at that time.

For most tutorials using Python you can install dependent modules to your environment by running the following commands.

# As current user
pip install -r requirements.txt

# As root user
sudo -E pip install -r requirements.txt

Note: If you are behind a corporate proxy you may need to set environment variables for https_proxy accordingly.

# If you are behind a corporate proxy
export https_proxy=https://<user>:<password>@<proxy_server>:<proxy_port>
# As current user
pip install -r requirements.txt

# If you are behind a corporate proxy
export https_proxy=https://<user>:<password>@<proxy_server>:<proxy_port>
# As root user
sudo -E pip install -r requirements.txt
