py-faster-rcnn:在windows上配置

0.先说一下本机配置

opencv2+cuda7.5+cudnn+anaconda，这些基础的之前都是配置好了的，python环境建议使用anaconda，用到的库基本都有了，好像没有easydict,自己装一下就好。

1.下载py-faster-rcnn

rbg大神github上的py-faster-rcnn

使用以下命令下载，直接download的话不完整

git clone --recursive https://github.com/rbgishick/py-faster-rcnn.git

2.编译lib

因为原版是在linux中使用的，在linux里可以直接编译，在windows下需要修改lib/setup.py，以下是修改后的

      description="Performs linear algebra computation on the GPU via CUDA",
      ext_modules=[cudamat_ext],
      cmdclass={'build_ext': CUDA_build_ext},
)

修改之后就可以编译了，将CMD定位到py-faster-rcnn目录下的lib文件夹，运行一下命令：

python setup.py install
python setup_cuda.py install

如果提示Microsoft Visual C++ 9.0 is required ...，在CMD中输入以下命令:

SET VS90COMNTOOLS=%VS110COMNTOOLS% （如果电脑中装的是vs2012）
SET VS90COMNTOOLS=%VS120COMNTOOLS% （如果电脑中装的是vs2013)

然后最后出现Finished processing ...就编译成功了。

3.编译pycaffe并替换到py-faster-rcnn目录下

之前已经安装了caffe的windows版，然后要编译pycaffe，打开buildVS2013下的工程，在pycaffe的属性中的预编译器中添加 WITH_PYTHON_LAYER，这样才会有Python类型的layer可以用

编译后将生成的文件，也就是caffe目录下python/caffe这个文件夹，整体复制到py-faster-rcnn目录下的caffe-fast-rcnn中python文件夹中并替换。

4.下载model文件

在data/scripts/fetch_faster_rcnn_models.sh中有个链接，可以在这里下载可用的models，文件600多兆，下完之后解压到data文件夹下（因为是.tar.gz压缩，记得解压两次），将解压完的文件夹faster_rcnn_models文件夹放在data目录下

另外，如果想替换成自己的caffemodel，需要修改faster_rcnn_test.pt文件，（在models\pascal_voc\VGG16目录下）

5.运行demo.py

然后就可以运行tools下的demo.py了,将CMD定位到tools目录

python demo.py

因为会导入cv2库，所以之前需要将opencv2/build/python/2.7/x64（也可能是x86）下的cv2.pyd复制到当前python的库搜索路径，可以使用sys.path来查看当前的搜索路径。

然后在运行demo.py出现有param_str_这个错误的话，就将lib文件夹下的rpn和roid_data_layer中的所有.py文件中的param_str_改成param_str,因为新版本的caffe中没有最后的下划线。
