latest ortools breaks populationsim so we froze the required package version

[bstabler]

@binnympaul "Looks like the new release of ortools (7.5.7466, released Jan 28) is breaking populationsim. I’m trying a run after installing the previous version of ortools (7.4.7247 )and PopulationSim seems to be running beyond the error point."

For the time being, after running pip install populationsim, run the following command:

pip install ortools==7.4.7247

This seems to be related to google/or-tools#1874

The latest version of ortools has some uncompiled binaries that require the VS C++ redistributable extra be installed on Windows 10.

Is this going to be the case for all the following versions? In my case, I don' think I could ship my code with this additional requirement.

@fpnick I think you meant to comment on google/or-tools#1874! PopulationSim would prefer not to ship with this requirement either! 😅

No, I did mean to comment here, I thought you knew more details about this :D

My issue over there was closed, so I don't have big hopes that they'll get rid of that again...

@fpnick Hoping they include all the precompiled stuff in future releases! Looks like the documentation has been updated to include the VS C++ installation though, so there's a possibility they'll leave this dependency around for a while :/
