【问题描述】：

我想在 Ubuntu 上的 Python3 上使用 SCIP。几乎一无所知。我找不到分步指南。我尝试安装界面“PySCIPOpt”得到了这个：

sudo python3 setup.py install

这是我经历的步骤：

下载 http://scip.zib.de/download.php?fname=scipoptsuite-5.0.1.tgz
解压到 /home/水晶/软件/SCIPSuide/SCIPOptSuite-5.0.1-Linux
导出 SCIPOPTDIR=/home/crystal/software/SCIPSuide/SCIPOptSuite-5.0.1-Linux
从 git 下载 PySCIPOpt-master
sudo python3 setup.py install 在提取的文件夹 PySCIPOpt-master 中

【问题讨论】：

下载 SCIP OPT 套件是不够的。您还必须make 和make install 它，请参阅these instructions。祝你好运

【解决方案1】：

为什么要从源代码编译所有内容？只需下载并运行Debian/Ubuntu installer for the SCIP Optimization Suite。然后运行pip install pyscipopt。

都解释了here。

我强烈建议在virtual environment 中为 Python 工作，而不是使用sudo 安装 Python 模块。您可能还想查看Anaconda 来组织您的 Python 环境。
