Windows workaround in `compile_model` #213

Goal

We might want to anticipate/circumvent issues with compiling the stan model in Windows, as a short-term fix for the Windows issues that @arranhamlet ran into. Longer term, we should probably pre-compile the model using instantiate.

Discussion:

Should we implement something in compile_model that sets the path for compiling the stan model to not be in the default Program Files location, which causes problems with model compilation because of the space. See @arranhamlet's workaround here

arranhamlet commented 1 day ago

My current workaround is to have a wrapper for the compile_model function (imaginatively called compile_model_upd) that looks for a space in the stan file path.

If it finds one, then it creates a new directory in a location that does not have a space, moves the stan files over, and points the compiler to these new files.

I am unsure how this would generalize across different work setups, I can envision running into permission issues.
