Error when setValue is given #55

Closed jac0320 closed 6 years ago

jac0320 commented 7 years ago

When using JuMP(0.15.0) & AmplNLWriter(0.3.0), error happens when setValue() is utilized with solver Bonmin (with intention of warm starting the value, not sure if Bonmin is supported, but there shouldn't be any error given the code fits different solvers). I attached the solving log below the error log.

Thanks!

It looks like the solver didn't produce a .sol file. Is this still an issue?

Closing as this now has a better error message
