This is tripping me up again in:

CI is failing with a 404 error. However, I can carry out the request.urlopen locally.

The 404 error you are running into is caused by using the old URL in the current orsopy version (should be fixed once the 1.2.3 release is done). I've asked ESS to instal a 308 forward from the old link and they didn't get it to work correctly so far.

I'll come back to you later about how to completely avoid internet access. What you can already consider is to define the density and fomula / sld in your model, then there shouldn't be a need to look up the database.

I'm using this approach. This code is the first time I came across trying to estimate mass density from a formula.

The old server redirect should work now. Check if that fixes your immedeate issue.
