There are a number of tutorials on all sorts of topics in this repo. To help you get started, here are some of the most useful topics in both R and Python.

• Intro to H2O in R
• H2O Grid Search & Model Selection in R
• H2O Deep Learning in R
• H2O Stacked Ensembles in R
• H2O AutoML in R

• Intro to H2O in Python
• H2O Grid Search & Model Selection in Python

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
