无法在Jupyter Notebook中导入Pyomo

Question

我正在尝试在 Jupyter Notebook 中导入 pyomo，我运行了以下代码：

!pip3 install pyomo

import pyomo

然后它回来了：

Requirement already satisfied: pyomo in /Users/*/Library/Python/3.8/lib/python/site-packages (5.7.3) Requirement already satisfied: PyUtilib>=6.0.0 in /Users/*/Library/Python/3.8/lib/python/site-packages (from pyomo) (6.0.0)

我想我已经安装了 pyomo，但是当我尝试导入模块时，找不到它。 请有人帮忙解决这个问题。

Answer 1

import pyomo

不起作用。正如文档中所写，您应该使用这个包，例如：

from pyomo.environ import *

或类似：

import pyomo.environ

Answer 2

conda install -c conda-forge pyomo - 通过此命令安装 pyomo，它可以工作
