How To Install Specific Versions Of H2o

I need to install an older version of H2O because model loading doesn't work even if the versions are just one apart (3.26.0.2 vs. 3.26.0.3). I'm struggling to find a page from whi

Solution 1:

The Changes.md file is the easiest place to look for links to where you can download every version. Just search for the version you want (e.g. "3.26.0.2") and you will see the URL there.

Click on the link and it will bring you to the download page for that version and you can click on the "Install in Python" tab which will show some code like this that you can copy/paste into your terminal:

# The following command removes the H2O module for Python.
pip uninstall h2o

# Next, use pip to install this version of the H2O Python module.
pip install http://h2o-release.s3.amazonaws.com/h2o/rel-yau/2/Python/h2o-3.26.0.2-py2.py3-none-any.whl

The URLs are "predictable" but you have to know the name of the release as well as the version number to correctly guess the URL.

Solution 2:

If you are installing h2o via pip, go to Release History page in the PyPi page for H2O. Look for the specific version you need and install that version based on the command provided over there. It should be similar to the following command.

pip install h2o==<<version no.>>
