Installation

These instructions have been taken from here

dynet is written in C++ with a python wrapper (there's also a scala wrapper!).
As a result, installing dynet requires three steps:

1. getting system requirements
2. compiling the C++ code
3. installing the python wrapper

Anytime you re-install or update dynet, you will be required to:

1. git pull from the dynet directory
2. compile the C++ code (step 2 above)
3. reinstall the python wrapper (step 3 above)

Getting system requirements

1. Install cython

pip install cython

Compiling the C++ code

1. Clone the dynet repository

mkdir dynet-base
cd dynet-base
git clone https://github.com/clab/dynet.git

2. Clone the eigen repository (requirement for matrix operations)

hg clone https://bitbucket.org/eigen/eigen -r 346ecdb

3. Compile C++ (this can take up to 10 minutes)

cd dynet
mkdir build
cd build
cmake .. -DEIGEN3_INCLUDE_DIR=../../eigen -DPYTHON=`which python`
make -j 2

Installing python wrapper

cd python
python ../../setup.py build --build-dir=.. --skip-build install

Testing it

From the root directory (dynet-base/dynet) of the dynet install, run this command:

python examples/python/xor.py

Windows installation

I have not tried installing for Windows, but instructions are here
