NVIDIA's fork of Caffe (NVIDIA version 0.11.0)

Detailed installation instructions are available on caffe's installation page. Condensed version is as follows:

Installing caffe prerequisites on Linux

% sudo apt-get install git
% cd $HOME
% git clone --branch v0.11.0 https://github.com/NVIDIA/caffe.git
% cd caffe
% sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler libatlas-base-dev
% sudo apt-get install python-dev python-pip gfortran
% cd python
% for req in $(cat requirements.txt); do sudo pip install $req; done

Installing caffe prerequisites on Mac OS

If you have homebrew installed, you can follow the instructions from caffe's installation page

Build caffe:

% cd $HOME/caffe
% cp Makefile.config.example Makefile.config
% make all --jobs=4
% make py

Set environment variables:

% export CAFFE_HOME=${HOME}/caffe

Install DIGITS

% cd $HOME
% git clone https://github.com/NVIDIA/DIGITS.git digits
% cd digits
% sudo apt-get install graphviz
% for req in $(cat requirements.txt); do sudo pip install $req; done

Again if on MacOS with homebrew, replace the last two lines as follows:

$ brew install graphviz
$ for req in $(cat requirements.txt); do pip install $req; done

Starting the server

You can run DIGITS in two ways:

digits-devserver

Starts a development server that listens on port 5000 (but you can change the port if you like - try running it with the --help flag).

digits-server

Starts a gunicorn app that listens on port 8080. If you have installed the nginx.site to your nginx sites-enabled/ directory, then you can view your app at http://localhost/.
