Ubuntu18.04安装caffe python3.6 opencv3.2 CPU

设置ubuntu的softwares&updates的源为国内源，这样会提高下载速度。

如果是安装python相关库，为提高速度使用：

pip3 install 要下载的库 -i https://国内源

安装caffe依赖库：

 # python3 modules (numpy, protobuf, skimage)
 sudo pip3 install numpy
 sudo apt-get install python3-skimage
 sudo apt-get install python3-protobuf

 # build essential
 sudo apt-get install build-essential cmake git pkg-config

 # gflags, glog, lmdb
 sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

 # boost
 sudo apt-get install libboost-all-dev

 # hdf5
 sudo apt-get install libhdf5-dev

 # protobuf
 sudo apt-get install protobuf-compiler libprotobuf-dev

 # blas
 sudo apt-get install libblas-dev libcblas-dev libatlas-base-dev libopenblas-dev

 # leveldb
 sudo apt-get install libleveldb-dev

 # snappy
 sudo apt-get install libsnappy-dev

安装opencv3.2

下载源代码 opencv-3.2.0.zip

 unzip opencv-3.2..zip
 cd opencv-3.2.
 mkdir release
 cd release
 cmake ..
 make -j4
 sudo make install

安装git:

sudo apt-get install git

安装caffe:

git clone https://github.com/BVLC/caffe

cd caffe
