ApplicationError:在Pyomo中找不到求解器的可执行文件

2022-04-17 00:00:00 python executable pyomo ipopt

问题描述

我正在学习Pyomo,并尝试使用ipopt来解决一个示例问题。但一开始,我已经安装了包,然后总是显示没有找到ipopt。之后,我重新安装了很多次,现在显示

'''WARNING: Could not locate the 'ipopt' executable, which is required for solver

报价

我不知道如何修复它,我在D桌安装了蟒蛇,而不是C桌。有谁能帮帮我,我一个月后有一次作业和考试需要它。谢谢。


解决方案

已通过安装最新版本的Anacondo和3.11版本的IPopt解决此问题
