CNTK安装

参考CNTK Binary Download and Configuration
1. sudo apt-get install g++
2. 确保openmpi的安装版本：dpkg -l | grep openmpi 参考MPI error while compiling
3. wget https://www.open-mpi.org/software/ompi/v1.10/downloads/openmpi-1.10.2.tar.gz
4. tar -xzvf ./openmpi-1.10.2.tar.gz
5. cd openmpi-1.10.2
6. ./configure –prefix=/usr/local/mpi
7. make -j all
8. sudo make install
9. export PATH=/usr/local/mpi/bin:$PATH
10. export LD_LIBRARY_PATH=/usr/local/mpi/lib:$LD_LIBRARY_PATH
11. 把下载的cntk文件解压到/home/majing目录下
12. export PATH=/home/majing/cntk/cntk/bin:$PATH
13. export LD_LIBRARY_PATH=/home/majing/cntk/cntk/lib:/home/majing/cntk/cntk/dependencies/lib:$LD_LIBRARY_PATH
14. export ACML_FMA=0
15. 验证安装：
- 到/media/majing/work下git clone https://github.com/Microsoft/CNTK
- 到Simple2d/Data目录下执行cntk configFile=../Config/Simple.cntk
16. 永久修改环境变量
(1) sudo vi /etc/profile
(2) 加入：
- export PATH=/usr/local/mpi/bin:$PATH
- export LD_LIBRARY_PATH=/usr/local/mpi/lib:$LD_LIBRARY_PATH
- export PATH=/home/majing/cntk/cntk/bin:$PATH
- export LD_LIBRARY_PATH=/home/majing/cntk/cntk/lib:/home/majing/cntk/cntk/dependencies/lib:$LD_LIBRARY_PATH
- export ACML_FMA=0
(3) source /etc/profile 每次打开新终端时都要执行
