# GraKeL: A library for graph kernels

**GraKeL** is a library compatible with the project of [scikit-learn](http://scikit-learn.org/)

Installation
=================

The GraKeL library requires:

* Python (>=2.7, >=3.5)
* NumPy (>=1.8.2)
* SciPy (>=0.13.3)
* Cython (>=0.27.3)
* cvxopt (>=1.2.0) [optional: lovasz]
* future (>=0.16.0) (for python 2.7)


Installing Dependencies
-----------------------

You can install the dependencies as follows:

```shell
$ pip install extension>=extension_version
```

or

```shell
$ pip install -r requirements.txt
```

Installing the *development-version*
------------------------------------

To install the *development-version* using [**pip**](https://pypi.org/project/grakel-dev) execute:

```shell
$ pip install grakel-dev
```

Getting Started
===============
Two pointers to get you started:


Testing
=======
You first need to build the package's c++ extensions
locally by executing:
```shell
$ python setup.py build_ext -i
```

To test the package, execute:
```shell
$ nosetests
```

For executing unit_tests or use a testing-interface for testing the `kernel` module:
```shell
$ python  grakel/tests/test_kernels.py --help
usage: test_kernels.py [-h] [--verbose] [--problematic] [--slow]
                       [--ignore_warnings] [--dataset DATASET] [--normalize]
                       [--develop | --all | --main]

A test file for all kernels

optional arguments:
  -h, --help         show this help message and exit
  --verbose          print kernels with their outputs on stdout
  --problematic      allow execution of problematic test cases in development
  --slow             allow execution of slow test cases in development
  --ignore_warnings  ignore warnings produced by kernel executions
  --dataset DATASET  chose the datset you want the tests to be executed
  --normalize        normalize the kernel output
  --develop          execute only tests connected with current development
  --all              execute all tests
  --main             execute the main tests [default]

```

For testing `graph_kernels`:
```shell
$ python grakel/tests/test_graph_kernel.py --help
usage: test_graph_kernels.py [-h] [--verbose] [--problematic] [--slow]
                             [--normalize] [--ignore_warnings]
                             [--dataset DATASET] [--develop | --all | --main]

A test file for all kernels

optional arguments:
  -h, --help         show this help message and exit
  --verbose          print kernels with their outputs on stdout
  --problematic      allow execution of problematic test cases in development
  --slow             allow execution of slow test cases in development
  --normalize        normalize the kernel output
  --ignore_warnings  ignore warnings produced by kernel executions
  --dataset DATASET  chose the datset you want the tests to be executed
  --develop          execute only tests connected with current development
  --all              execute all tests
  --main             execute the main tests [default]

```

And for testing the `Graph` class:
```shell
$ python grakel/tests/test_graph.py --help
usage: test_graph.py [-h] [--verbose] [--ignore_warnings]

A test file for all `Graph` type objects

optional arguments:
  -h, --help         show this help message and exit
  --verbose          verbose outputs on stdout
  --ignore_warnings  ignore warnings produced by kernel executions
```
You can also execute the kernel test locally through a *test-main-function* as

```shell
$ python -m grakel.tests
```

Contributing
============
To learn how to integrate your own kernel and how to contribute to the GraKeL project, please read the sections *Write your own kernel* and *Contributing* in the [Documentation][doc], respectively.

License
=======
GraKeL comes with a __BSD 3-clause__ license (as with scikit-learn).
It contains the C++ source code of [BLISS](http://www.tcs.hut.fi/Software/bliss) (a library for graph isomorphism) which is __LGPL__ licensed.
Futhermore its optional dependency in the package of [cvxopt](https://cvxopt.org/) (a tool for solving convex-optimization problems) comes with a __GPL__ license.
