}" - но это не помогло - теперь ошибки или исключения не выбрасывается но вижу что манипулятор просто каждый раз становится горизонтально что свидетельствует о том что на самом деле оптимизации не происходит а в окне вывода результатов вижу очень большое число функционала, запускаю приложение через mpiexec, если буду просто запускать приложение через отладчик то даже в одномерных задачах увижу такую ошибку что манипулятор становится горизонтально, при запуске через mpiexec - одномерная задача корректно решается optuna, но двумерная и больше уже не решается, а iOpt не решает даже одномерной как не запускай, причём сами скрипты точно верны - тут дело в другом
