Better error when no solution found

marcosfelt opened this issue · comments

Currently, when the solver doesn't find a solution, it raises a generic exception. Using a generic exception makes it difficult to specifically catch failed solutions and do custom error handling.

GEKKO/gekko/gekko.py

Line 2140 in 3e2698a

raise Exception(apm_error)

Would you accept a PR that creates a custom error for failed solutions?

Try setting debug=0 to allow the code to proceed without the exception with m.solve(debug=0). The status is reported by m.options.APPSTATUS or m.options.APPINFO for more specific error information.
