ubuntu16.04下安装配置caffe2和detectron（亲测有效，非常简单）

介绍

Detectron是FAIR推出的一款优秀的物体检测、分割框架，基于caffe2，其中包含了Faster RCNN、Mask RCNN、FPN、RetinaNet、R-FCN、Openpose等常见的模型。可能是由于何凯明的缘故吧，Facebook集成了许多他提出的模型。该框架可以很方便的把这些模型应用到自己的工程和项目中，下面将具体介绍如何安装和配置caffe2和detectron。

安装配置caffe2

caffe2的安装网上教程有很多，但是有可能安装不成功，facebook开源的pytorch框架已经把caffe2集成到里面去啦～所以只需要安装pytorch即可。首先安装下依赖环境：

$ sudo apt-get update
$ sudo apt-get install -y --no-install-recommends \build-essential \cmake \git \libgoogle-glog-dev \libgtest-dev \libiomp-dev \libleveldb-dev \liblmdb-dev \libopencv-dev \libopenmpi-dev \libsnappy-dev \libprotobuf-dev \openmpi-bin \openmpi-doc \protobuf-compiler \python-dev \python-pip                          
$ sudo pip install \future \numpy \protobuf# for Ubuntu 16.04
$ sudo apt-get install -y --no-install-recommends libgflags-dev

然后进入pytorch官网 "https://pytorch.org"找到适合自己的pytorch版本，然后根据推荐的指令进行安装即可，在这里我的是 pip3 install torch torchvision

然后在命令栏中进行安装即可。安装完成之后，进行测试，没有报错，说明安装成功。

Type "help", "copyright", "credits" or "license" for more information.
>>> import caffe2
>>>

当出现No module named ‘past’ 错误之后，进行以下两个命令即可：

pip install future
pip install --upgrade future

当下面测试通过时，说明caffe2的安装配置成功啦～

$ python3 -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"
Success
$ python3 -c 'from caffe2.python import workspace; print(workspace.NumCudaDevices())'

安装配置detectron

当完成caffe2的环境搭建之后，就可以配置detectron啦～，首先需要把源文件下载到本地

git clone https://github.com/facebookresearch/detectron

然后转到detectorn文件夹内：

pip install -r requirements.txt如果权限不够的话：
pip install --user -r requirements.txt

接着：

make

make完成之后就算配置好detectron啦，下面来测试下，是否配置成功，进入requirements.txt目录下：

python detectron/tests/test_spatial_narrow_as_op.py

出现以下结果即是配置成功：

oliver@oliver-System-Product-Name:~/detectron$ python detectron/tests/test_spatial_narrow_as_op.py
