Notes on setting up cuda on an ubuntu machine.

1 ) Download cuda 7.5 deb

2. Install cuda

sudo dpkg -i cuda-repo-ubuntu1504-7-5-local_7.5-18_amd64.deb
sudo apt-get update
sudo apt-get install cuda

3. Add cuda to path

nano ~/.bashrc

export CUDA_HOME=/usr/local/cuda-7.5
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64

PATH=${CUDA_HOME}/bin:${PATH}
export PATH

4. (optional) check cuda works make a copy of the samples and build them

rsync -av /usr/local/cuda/samples  .
cd samples/
make -j4
bin/x86_64/linux/release/deviceQuery

Hopefully you will see a message containing

Detected 1 CUDA Capable device(s)

5. Download Cuda DNN Nvidia’s DNN can speed up the neural net learning

You need to do a free registration

6. Install Cuda DNN

tar -xvf cudnn-7.0-linux-x64-v3.0-prod.tgz
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/* /usr/local/cuda/include/

7. Install cnnem

cd cnmem
mkdir build
cd build
cmake ..
make
sudo cp include/cnmem.h /usr/local/cuda/include
sudo cp build/*.so  /usr/local/cuda/lib64/
