Install caffe on ubuntu 14.04 with cuda-6.5.14

My device:

1. OS: ubuntu 14.04
2. linux kernel: 3.13.0-39
3. graphic card: nvidia gtx 660

(I can't promise that this way can do well on laptop which graphic card include nvidia Optimus mechanisum)

1. Install CUDA (include nvidia driver)
• Install build essential

sudo apt-get update && sudo apt-get install build-essential

• Download CUDA and Extract

wget http://developer.download.nvidia.com/compute/cuda/6_5/rel/installers/cuda_6.5.14_linux_64.run

chmod a+x cuda_6.5.14_linux_64.run

mkdir nvidia_installer

./cuda_6.5.14_linux_64.run -extract=`pwd`/nvidia_installer

• Press Ctrl-Alt-F1 and login
Stop the lightdm and remove current nvidia driver

sudo service lightdm stop
sudo apt-get remove --purge nvidia-*
# If it returns there are some process cause it can't be remove, i just kill them all and remove again.



2. Install

cd nvidia_installer
sudo ./NVIDIA-Linux-x86_64-340.29.run
sudo ./cuda-linux64-rel-6.5.14-18749181.run
sudo ./cuda-samples-linux-6.5.14-18745345.run
# restart lightdm and disable nouveaus
sudo service lightdm start

(I set every settings by default!)
3. Disable nouveau

gedit /etc/modprobe.d/blacklist-nouveau.conf

and add

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

Reboot

update-initramfs -u
sudo reboot

4. Other necessary libs.
cudnn api download (Login and answer some questions to get the download permission.)

tar -xzvf cudnn-6.5-linux-R1.tgz
cd cudnn-6.5-linux-R1
sudo cp lib* /usr/local/cuda/lib64/
sudo cp cudnn.h /usr/local/cuda/include/

sudo cp lib* /usr/local/lib
sudo cp cudnn.h /usr/local/include
sudo ln -sf /usr/local/lib/libcudnn.so.6.5.18 /usr/local/lib/libcudnn.so.6.5

OpenBLAS

git clone https://github.com/xianyi/OpenBLAS
cd OpenBLAS
make
mkdir build
make install PREFIX=build

leveldb

git clone https://github.com/google/leveldb
cd leveldb
make
sudo cp --preserve=links libleveldb.* /usr/local/lib
sudo cp -r include/leveldb /usr/local/include/
sudo ldconfig

others

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libboost-all-dev libhdf5-serial-dev libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler

5. Install caffe and testing

git clone https://github.com/BVLC/caffe
cd caffe
cp Makefile.config.example Makefile.config
gedit Makefile.config

• USE_CUDNN := 1
• BLAS := open
• BLAS_INCLUDE := your-path-to-blas/OpenBLAS/build/include
• BLAS_LIB := your-path-to-blas/OpenBLAS/build/lib
install
