virtualenv 下安装caffe教程

　1.首先安装依赖环境，

% sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler libatlas-base-dev
% sudo apt-get install --no-install-recommends libboost-all-dev
% sudo apt-get install python-dev python-pip python-numpy gfortran

2.然后创建 virtual --system-site-packages caffe-env,执行 source bin/activate,

3.运行 for req in $(cat requirements.txt); do pip install $req; done 安装python需求环境

4.进入caffe文件夹，修改Makefile.config，将PYTHON_INCLUDE和PYTHON_LIB 修改为caffe-env中的路径

5.并修改环境变量：

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/caffe/build/lib # contains libcaffe.so
$ export PYTHONPATH=$PYTHONPATH:/path/to/caffe/python

6.然后 make -j8| make test -j8 | make runtest
