在Ubuntu 16上安装PySCIPOpt

Question

我想在Ubuntu上的Python3上使用SCIP。几乎毫无头绪。我一步一步地找不到向导。我试图安装接口"PySCIPOpt“，我得到了以下信息：

sudo python3 setup.py install
Installing collected packages: PySCIPOpt
Running setup.py install for PySCIPOpt ... error

以下是我所经历的步骤：

1. 下载http://scip.zib.de/download.php?fname=scipoptsuite-5.0.1.tgz
2. 将其提取到/home/crystal/software/SCIPSuide/SCIPOptSuite-5.0.1-Linux中
3. 导出SCIPOPTDIR=/home/crystal/software/SCIPSuide/SCIPOptSuite-5.0.1-Linux
4. 从git下载PySCIPOpt母版
5. 提取文件夹中的sudo python3 setup.py install

Answer 1

为什么要从源代码编译所有内容？只需下载并运行SCIP优化套件的Debian/Ubuntu安装程序即可。然后运行pip install pyscipopt。

这一切都解释了这里。

我强烈建议在虚拟环境中使用Python，而不是使用sudo安装Python模块。您还可能希望查看蟒蛇来组织您的Python环境。
