sudo apt-get install git lua5.2 luarocks luajit libprotobuf-dev protobuf-compiler
curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | bash
test torch:
luajit -ltorch
install loadcaffe:
sudo luarocks install loadcaffe
if you have an old version of gcc you have to (source):
git clone https://github.com/szagoruyko/loadcaffe
cd loadcaffe
nano CMakeLists.txt
change the line: add_definitions(-std=c++11) to: add_definitions(-std=c++0x)
luarocks make
then:
sudo luarocks install image
sudo luarocks install nn
to install cuda support:
sudo luarocks install cutorch
sudo luarocks install cunn
but since the max allocable memory is the max memory of your gpu it is best to use cudnn, you have to register here: https://developer.nvidia.com/cudnn, then download the package and install (source):
tar -xvzf cudnn-7.0-linux-x64-v4.0-prod.tgz
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/cudnn.h /usr/local/cuda/include/
sudo luarocks install cudnn
and test it by running:
th neural_style.lua -gpu 0 -backend cudnn
if you have problems running it and it gives the error (source):
[CUT] ‘libcudnn (R4) not found in library path.
Please install CuDNN from https://developer.nvidia.com/cuDNN
Then make sure files named as libcudnn.so.4 or libcudnn.4.dylib are placed in your library load path (for example /usr/local/lib , or manually add a path to LD_LIBRARY_PATH)
you have to set the library path correctly:
export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH
now we can create our work folder and clone the git repo of the neuralnetwork,
it’s nice to do that were we a bit of space since it will use about ~600MB:
sudo git clone https://github.com/jcjohnson/neural-style.git
cd neural-style
now we can download the model, it will take a bit:
sudo sh models/download_models.sh
