detectron2是Facebook研发并开源的目标检测平台，包含了大量业内最具代表性的目标检测、图像分割、关键点检测算法等。Detectron2基于新版的Pytorch进行更新，包含了更大的灵活性与扩展性。

笔者将在本文中介绍如何在windows系统中安装Detectron2

首先按照官方文件指导，只需要下载相关代码，然后pip 即可，具体两行命令如下：

git clone https://github.com/facebookresearch/detectron2.git
python -m pip install -e detectron2

笔者在执行第一行命令进行下载的时候，完全没有问题。但是第二行则直接报错，相关错误如下：

  note: This error originates from a subprocess, and is likely not a problem with pip.

笔者经查询，解决方案如下：

第一步：安装java jdk并设置系统变量和环境变量

第二步：根据python版本选择Jpype进行安装 https://www.lfd.uci.edu/~gohlke/pythonlibs/#jpype

第三步： 安装Microsoft C++ 生成工具 - Visual Studio ：https://visualstudio.microsoft.com/zh-hans/visual-cpp-build-tools/
