Пожалуйста, объясните, что я должен делать медленно. Я пытаюсь установить cvxpy на свой компьютер. Я установил инструменты сборки python, Visual Studio и попробовал в командной строке, но при попытке установить получил ошибки. Поэтому я отказался от этой идеи и установил anaconda, и теперь я могу установить и провалить тесты носа.

Обновление: я не смог включить весь журнал, потому что он был слишком длинным и был помечен как спам. Контекст таков: я мало что помню о программировании, но в свое время я этому научился. Я пытаюсь установить cvxpy, чтобы использовать функцию геометрического программирования. Я использую инструкции на cvxpy.org для установки на Windows, показанные ниже:
