问题
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 which I can find the download links. Why doesn't it exist? All software have an archive or older versions page for this. I also tried playing with the link to current version but no luck as it doesn't have a pattern you could guess. So how can I install H2O 3.26.0.2 in Python (pip)?
Looked all over the web and documentation
model = h2o.load_model("H2O.model_name.zip")
Error: Found version 3.26.0.2, but running version 3.26.0.3
Request: POST /99/Models.bin/
data: {'dir': 'H2O.model_name.zip'}```

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.
