INSTALL.md

Installing the pyCNN module.

First, get CNN and Eigen:

mkdir cnn
cd cnn
git clone https://github.com/yoavg/cnn.git
hg clone https://bitbucket.org/eigen/eigen/

Compile CNN. Note that we are currently relying on the CNN code that is in the pycnn branch (it has a few modifications needed for pyCNN to work), but at some point this will be merged into cnn proper. (modify the code below to point to the correct boost location)

cd cnn
git checkout pycnn # branch
mkdir build
cd build
cmake .. -DEIGEN3_INCLUDE_DIR=../eigen -DBOOST_ROOT=/home/yogo/.local/boost_1_58_0 -DBoost_NO_BOOST_CMAKE=ON
make -j 2

Now that CNN is compiled, we need to compile the pycnn module. This requires having cython installed. If you don't have cython, it can be installed with either pip install cython or better yet conda install cython.

pip2 install cython --user
cd ../pycnn
make
make install

We are almost there. We need to tell the environment where to find the compiled cnn shared library. The pyCNN's make fetched a copy of libcnn_shared.so and put it in the pycnn lib.

Add the following line to your profile (.zshrc or .bashrc), change according to your installation location.

export LD_LIBRARY_PATH=/home/yogo/cnn/cnn/pycnn

Now, check that everything works:

# check that it works:
cd ..
cd pyexamples
python2 xor.py
python2 rnnlm.py rnnlm.py
