The Dynamic Neural Network Toolkit

General

DyNet is a neural network library developed by Carnegie Mellon University and many others. It is written in C++ (with bindings in Python) and is designed to be efficient when run on either CPU or GPU, and to work well with networks that have dynamic structures that change for every training instance. For example, these kinds of networks are particularly important in natural language processing tasks, and DyNet has been used to build state-of-the-art systems for syntactic parsing, machine translation, morphological inflection, and many other application areas.

Read the documentation to get started, and feel free to contact the dynet-users group group with any questions (if you want to receive email make sure to select "all email" when you sign up). We greatly appreciate any bug reports and contributions, which can be made by filing an issue or making a pull request through the github page.

You can also read more technical details in our technical report.

Getting started

You can find tutorials about using DyNet here (C++) and here (python), and here (EMNLP 2016 tutorial).

One aspect that sets DyNet apart from other tookits is the auto-batching feature. See the documentation about batching.

The example folder contains a variety of examples in C++ and python.

Installation

DyNet relies on a number of external programs/libraries including CMake,
Eigen, and Mercurial (to install Eigen). CMake, and Mercurial can
be installed from standard repositories.

For example on Ubuntu Linux:

sudo apt-get install build-essential cmake mercurial

Or on macOS, first make sure the Apple Command Line Tools are installed, then
get CMake, and Mercurial with either homebrew or macports:

xcode-select --install
brew install cmake hg  # Using homebrew.
sudo port install cmake mercurial # Using macports.

On Windows, see documentation.

To compile DyNet you also need the development version of the Eigen
library
. If you use any of the
released versions, you may get assertion failures or compile errors.

If you don't have Eigen already, you can get it easily using the
following command:

hg clone https://bitbucket.org/eigen/eigen/ -r b2e267d

The -r NUM specified a revision number that is known to work. Adventurous
users can remove it and use the very latest version, at the risk of the code
breaking / not compiling. On macOS, you can install the latest development
of Eigen using Homebrew:

brew install --HEAD eigen

C++ installation

You can install dynet for C++ with the following commands

# Clone the github repository
git clone https://github.com/clab/dynet.git
cd dynet
mkdir build
cd build
# Run CMake
# -DENABLE_BOOST=ON in combination with -DENABLE_CPP_EXAMPLES=ON also
# compiles the multiprocessing c++ examples
cmake .. -DEIGEN3_INCLUDE_DIR=/path/to/eigen -DENABLE_CPP_EXAMPLES=ON
# Compile using 2 processes
make -j 2
# Test with an example
./examples/train_xor

For more details refer to the documentation

Python installation

You can install DyNet for python by using the following command

pip install git+https://github.com/clab/dynet#egg=dynet

For more details refer to the documentation
