简介
本指南将帮助您开始使用 Python 中的 OR-Tools,
示例。
虽然这些说明可能也适用于其他 Windows 版本,
仅在满足以下要求的计算机上进行了测试:
Windows 10 64 位 (x86_64),带有:
- Microsoft Visual Studio 企业版 2022
- Microsoft Visual Studio 社区 2022 预览版 2 或更高版本
前提条件
以下各部分介绍了安装 OR-Tools 的前提条件。
Microsoft Visual C++ 可再分发
您必须将
已安装 Microsoft Visual C++ 可再分发 for Visual Studio 2022(选择 x64 版本)
因为适用于 Python 的 OR-Tools 库是
C++ 原生库。
Python
您必须安装以下任一版本的 Python:
然后验证您的 PATH 中是否提供了 pip 9.01 或更高版本:
python --version
python -c "import platform; print(platform.architecture()[0])"
python -m pip --version
假设您的 Windows 上已安装必备软件,请按以下步骤操作:
python3 -m pip install -U --user ortools
或者,如需在系统范围内安装,请执行以下操作:
sudo python3 -m pip install -U ortools
如需卸载 OR-Tools,请发出以下命令:
python3 -m pip uninstall ortools
获取 Python 示例代码
示例代码位于
python_or-tools 代码库中。
以 zip 文件的形式下载代码库
并将其解压缩,或者克隆代码库:
git clone -b v9.10 --depth 1 https://github.com/or-tools/python_or-tools
切换到示例目录:
cd python_or-tools
运行示例
在 python_or-tools
目录下:
使用以下命令运行二进制文件:
python3 basic_example.py
恭喜!您刚刚使用 OR-Tools 运行了一个应用,
开始使用 OR 工具。
