接上一篇重装系统后。
要和先前的工作接轨，所以还得安装Ｄｅｔｅｃｔｒｏｎ（https://github.com/facebookresearch/Detectron/blob/master/INSTALL.md）；中间有个小插曲，就是刚巧看见原作者又发布的 maskrcnn-benchmark ，速度较 Ｄｅｔｅｃｔｒｏｎ 快了一倍，等我屁颠的装完后，发现只能跑物体检测和语义分割，不能做关键点检测。所以还是得回到先前的Ｄｅｔｅｃｔｒｏｎ上。
注意，这里需要的是Ｐｙｔｈｏｎ２．７，而我之前安装了Ａｎａｃｏｎｄａ３（Ｐｙｔｈｏｎ３．５），怎么办呢？ 利用ｃｏｎｄａ创建一个虚拟环境，里面是Ｐｙｔｈｏｎ２．７就好了。
>> conda create -n detectron_py27 python=2.7 #激活该环境的意思就是，优先使用该环境下的Ｐｙｔｈｏｎ >> source activate detectron_py27 >> echo $PATH /home/wang/anaconda3/envs/detectron_py27/bin:/usr/local/cuda-9.0/bin:/home/wang/anaconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin #退出该环境 source deactivate
然后就是安装caffe2以及cocoapi：
＃直接安装pytorch１．０，里面包含了ＣＡＦＦＥ２ >> conda install pytorch-nightly -c pytorch #接着是cocoapi >> cd ~/codes >> git clone https://github.com/cocodataset/cocoapi.git >> cd cocoapi/PythonAPI >> make install
最后安装detectron，由于我的代码是老一代版本，所以跟现在还是不一样的。
>> cd ~/codes >> git clone https://github.com/facebookresearch/detectron >> cd detectron/lib && make
然后就是测试是否安装成功，这里需要注意，由于是直接用ｃｏｎｄａ安装的caffe2，因此其ｌｉｂ文件并不在 /usr/local下，所以测试时，会报错

打印一下变量prefixes中保存的路径：
[u‘/usr/local‘, ‘/home/wang/anaconda3/envs/detectron_py27‘, ‘/home/wang/anaconda3/envs/detectron_py27‘, ‘/home/wang/codes/detectron_old/tests‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python27.zip‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/plat-linux2‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/lib-tk‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/lib-old‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/lib-dynload‘, ‘/home/wang/.local/lib/python2.7/site-packages‘, ‘/home/wang/codes/detectron_old/lib‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/site-packages‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/site-packages/pycocotools-2.0-py2.7-linux-x86_64.egg‘, ‘/home/wang/anaconda3/envs/detectron_py27/lib/python2.7/site-packages‘]
而libcaffe2_detectron_ops_gpu.so存在的路径却是
‘/home/wang/anaconda3/pkgs/pytorch-nightly-1.0.0.dev20181029-py2.7_cuda9.0.176_cudnn7.1.2_0/lib/python2.7/site-packages/torch/lib/libcaffe2_detectron_ops_gpu.so’
所以需要将此路径添加到 prefixes 中。保存 detectron/lib/utils/env.py 重新测试，就通过了。
