HiGHS 1.13.1 solver option HiPO on Windows 11

[arg...@gmail.com]

I have installed the new HiGHS version 1.13.1 on my Windows 11 laptop with pip install. However, when I call it from Pyomo with SolverFactory highs or appsi_highs using the HiGHS solver option hipo, I get this message

ERROR:   The HiPO solver was requested via the "solver" option, but this build was compiled without HiPO support. Reconfigure with FAST_BUILD=ON and -DHIPO=ON to enable HiPO.

Does anybody know how to solve it?

Andrés,

 

In the future, providing a small (“minimum working”) example that we can use to reproduce your problem would really help the people on this list give you answers/suggestions.

 

That said, based on your description, this looks like an issue with how the pip distribution of highspy was compiled.  Your best bet at more information is to raise your question with the HiGHS / highspy developers.

 

Best regards,

John

I have used a modified version of a pyomo test
