Python Bindings

How to install this

This project is currently work in progress, and is to be considered for all intents and porposes an alpha version.

To install the latest (alpha) release, run the following:

pip install ensmallen_graph

Compile the bindings

The project uses PyO3 and maturin. You need nightly rust in order to compile PyO3. This could be done by running:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh --default-toolchain nightly --profile default -y

Then we need to install maturin with:

cargo install maturin

And finally we can create the Wheels with:

maturin build --release

The wheels will be located in ./target/wheels/.

Compile the bindings for multiple Python versions

By default maturin will build for the installed python version.

To install other Python versions just run:

wget https://www.python.org/ftp/python/${PYTHON_VERSION}/Python-${PYTHON_VERSION}.tar.xz
tar -xf Python-${PYTHON_VERSION}.tar.xz
(cd Python-${PYTHON_VERSION}; ./configure --enable-optimizations; make -j$(nproc); make -j$(nproc) install)

Where ${PYTHON_VERSION} is the choosen version, such as 3.8.3 or 3.6.10.

Solving the GLIBC__2.29__ not found error

This means that the linux package were built on a system with a really new Libc version. This can be solved by compiling your own bindings. In order to be compatible with as many systems as possible, we suggest to build them on Ubuntu 16.04 .

Exploiting Avx

The library vec_rand which is used in the crate can take advantage in using Avx instructions/

To compile the bindings with Avx Instructions you can run :

RUSTFLAGS=" -C target-cpu=native" maturin build --release --no-sdist
