# Python binding for the nGraph Library

## Build the nGraph Library (required)

Follow the [build instructions] to build nGraph. When you get to the cmake command, be sure to specify the option that enables ONNX support in the Library:

$ cmake ../ -DNGRAPH_ONNX_IMPORT_ENABLE=ON

Next, clone the pybind11 repository:

$ cd ngraph/python $ git clone –recursive https://github.com/pybind/pybind11.git

Set the environment variables:

export NGRAPH_CPP_BUILD_PATH=$HOME/ngraph_dist export LD_LIBRARY_PATH=$HOME/ngraph_dist/lib export DYLD_LIBRARY_PATH=$HOME/ngraph_dist/lib # (Only needed on MacOS) export PYBIND_HEADERS_PATH=pybind11

Install the wrapper (Python binding):

$ python setup.py install

Unit tests require additional packages be installed:

$ pip install -r test_requirements.txt

Then run a test:

$ pytest test/test_ops.py $ pytest test/ngraph/

## Running tests with tox

[Tox] is a Python [virtualenv] management and test command line tool. In our project it automates:

• running of unit tests with [pytest]

• checking that code style is compliant with [PEP8] using [Flake8]

• static type checking using [MyPy]

• testing across Python 2 and 3

Installing and running test with Tox:

$ pip install tox $ tox

You can run tests using only Python 3 or 2 using the -e (environment) switch:

$ tox -e py36 $ tox -e py27

You can check styles in a particular code directory by specifying the path:

$ tox ngraph/

If you run into any problems, try recreating the virtual environments by deleting the .tox directory:

$ rm -rf .tox $ tox
