Best Practices for Posting Questions

Please read before posting a question:

  • Search the General Discussion community to see if your question has already been answered.
  • Search the H2O User Guide or any of the other documentation resources at docs.h2o.ai.
  • Try not to post a duplicate question if possible.
  • For questions that don’t involve code about an H2O product and its software features, such as "where can I find an example of Driverless AI Machine Learning model deployment in Java Runtime or C++ Runtime?, "how can I use GPUs with H2O Driverless AI?",..., please post those questions in the General Discussions community, include the appropriate tags and our H2O developers will respond.
  • For code questions, if you have not read Stackoverflow’s Minimal, Complete and Verifiable Example (MCVE) article, we encourage you to read it, then make your post in the General Discussions community.  Please use the appropriate tag(s) for your question.
  • For bug reports or feature requests, you can file support tickets directly in our issue tracking system located here: https://support.h2o.ai/support/home  When filing a bug report, please make sure to include a reproducible example if possible and H2O product version & client (R, Python, etc) information.
