Сбой теста Pulp.pulpTestAll () при «Тестировании нулевого ограничения»

0 голосов
/ 04 июля 2018

Я использую anaconda версии 1.6.14, python версии 3.6.5, целлюлозы версии 1.6.8 и CPLEX версии 12.8.

Когда я запускаю pulp.pulpTestAll (), монеты проходят, и CPLEX_CMD дает сбой при тестировании нулевого ограничения (см. Вывод ниже).

В этом вопросе приведены те же выходные данные: Сбой теста Pulp.pulpTestAll (), слишком много значений для распаковки Но вопрос в том, почему GUROBI потерпел неудачу, а не в CPLEX, и поэтому ответы, представленные там, не отвечают на мой вопрос.
