Summary/Motivation:
This resolves recent test failures in the GHA singletest job. MAiNGOpy (@MAiNGO-github) released a new version yesterday (8.1) that only included wheels for Windows. Unfortunately, the MAiNGOpy
setup.py
has an unconditional required import ofskbuild
(which is not present in the Pyomo GHA environment), so the build ofmaingopy
fails on Linux & OSX. This highlighted that thepyomo.contrib.appsi.solvers.maingo_solvermodel
module is not importable withoutmaingopy
(leading to the test failure).This PR resolves that test failure (but not the availability of
maingopy
on GHA Linux / OSX builds).Changes proposed in this PR:
maingopy
within theappsi_maingo
solver so that module imports do not fail ifmaingopy
is missingLegal Acknowledgement
