记intel杯比赛中各种bug与debug【其一】：安装intel caffe
因为intel杯创新软件比赛过程中，并没有任何记录。现在用一点时间把全过程重演一次用作记录。
学习 pytorch 一段时间后，intel比赛突然不让用 pytoch 了，于是打算转战intel caffe。
ArchLinux 安装intel caffe 失败
首先安装caffe依赖，安装intel mkl，最后编译安装intel caffe
# yaourt -S caffe-git 这句话就可以直接安装caffe，但看起来不是intel caffe
git clone http://github.com/intel/caffe
cd caffe
cp Makefile.config.example Makefile.config
nano Makefile
make all -j4
安装intel mkl时出现问题，发现其不支持arch，问题挺多不如直接安装一个ubuntu
然后转战ubuntu，正好家里有一个旧的移动硬盘
云备份数据，安装ubuntu
Ubuntu16.04 安装intel caffe成功
这里ubuntu的安装就不写了
主要注意旧硬盘需要写gpt分区表，若用于efi启动，需要fat32格式的/boot/efi
caffe安装参考：https://software.intel.com/zh-cn/articles/training-and-deploying-deep-learning-networks-with-caffe-optimized-for-intel-architecture
一样首先安装依赖
sudo apt-get update &&
sudo apt-get -y install build-essential git cmake &&
sudo apt-get -y install libprotobuf-dev libleveldb-dev libsnappy-dev &&
sudo apt-get -y install libopencv-dev libhdf5-serial-dev protobuf-compiler &&
sudo apt-get -y install --no-install-recommends libboost-all-dev &&
sudo apt-get -y install libgflags-dev libgoogle-glog-dev liblmdb-dev &&
sudo apt-get -y install libatlas-base-dev
对于Ubantu16.04，链接库
find .-type f -exec sed -i -e 's^"hdf5.h"^"hdf5/serial/hdf5.h"^g' -e 's^"hdf5_hl.h"^"hdf5/serial/hdf5_hl.h"^g' '{}' ;
cd /usr/lib/x86_64-linux-gnu
sudo ln -s libhdf5_serial.so.10.1.0 libhdf5.so
sudo ln -s libhdf5_serial_hl.so.10.0.2 libhdf5_hl.so
安装intel mkl
首先免费注册申请Intel® Performance Libraries
注册成功会受到一封邮件
下载并按.sh安装，安装过程略了
于是开始调整config，编译
git clone http://github.com/intel/caffe
cd caffe
cp Makefile.config.example Makefile.config
nano Makefile
make all -j4
附上Makefile.config
主要处理mkl，python路径

Q ?= @
编译过程中会出现一些warning，然而发现并没有什么大问题
至此intel caffe安装成功
安装成功后
1.注意添加export PYTHONPATH=$PYTHONPATH:=<your caffe path>/python
不然会有如下报错
import caffe
#Traceback (most recent call last):
# File "<stdin>", line 1, in <module>
# File "/usr/local/lib/python3.5/dist-packages/caffe/__init__.py", line 37, in <module>
# from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver
# File "/usr/local/lib/python3.5/dist-packages/caffe/pycaffe.py", line 49, in <module>
# from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
#ImportError: libcaffe.so.1.1.0: cannot open shared object file: No such file or directory
2.注意使用python2.7
如果使用python3
import caffe
#Traceback (most recent call last):
# File "<stdin>", line 1, in <module>
# File "/home/tanglizi/caffe/python/caffe/__init__.py", line 37, in <module>
# from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver
# File "/home/tanglizi/caffe/python/caffe/pycaffe.py", line 49, in <module>
# from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
#ImportError: dynamic module does not define module export function (PyInit__caffe)
3.顺便把caffe链接到/usr/bin下面，方便使用
ln -s <your caffe path>/build/tools/caffe /usr/bin/
