DIGITS is only officially supported on Ubuntu 14.04. However, DIGITS has been successfully used on other Linux variants as well as on OSX.
DIGITS depends on several third-party libraries.
The CUDA toolkit (>= CUDA 6.5) is highly recommended, though not technically required.
- Download from the CUDA website
- Follow the installation instructions
- Don't forget to set your path. For example:
CUDA_HOME=/usr/local/cudaLD_LIBRARY_PATH=$CUDA_HOME/lib64:$LD_LIBRARY_PATH
For greater performance, you can also install cuDNN.
- Download from the cuDNN website
- Follow the installation instructions
- You can copy the files directly into your CUDA installation
cp -a libcudnn* $CUDA_HOME/lib64/cp cudnn.h $CUDA_HOME/include/
At least one deep learning framework backend is required.

- Torch7 - coming soon
% cd $HOME
% git clone https://github.com/NVIDIA/DIGITS.git digits
Throughout the docs, we'll refer to your install location as DIGITS_HOME ($HOME/digits in this case), though you don't need to actually set that environment variable.
Several PyPI packages need to be installed. The recommended installation method is using a virtual environment (installation instructions).
% cd $DIGITS_HOME
% pip install -r requirements.txt
If you want to install these packages without using a virtual environment, replace "pip install" with "sudo pip install".
DIGITS uses graphviz to visualize network architectures. You can safely skip this step if you don't want the feature.
% sudo apt-get install graphviz
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).
Then, you can view your server at http://localhost:5000/.
% ./digits-server
Starts a production server (gunicorn) that listens on port 8080 (http://localhost:8080). If you get any errors about an invalid configuration, use the development server first to set your configuration.
If you have installed the nginx.site to your nginx sites-enabled/ directory, then you can view your app at http://localhost/.
