# DeepProbLog
[](https://github.com/ML-KULeuven/deepproblog/actions/workflows/python-app.yml)
DeepProbLog is an extension of [ProbLog](https://dtai.cs.kuleuven.be/problog/)
that integrates Probabilistic Logic Programming with deep learning by introducing the neural predicate.
The neural predicate represents probabilistic facts whose probabilites are parameterized by neural networks.
For more information, consult the papers listed below.
## Installation
DeepProbLog can easily be installed using the following command:
Make sure the following packages are installed:
```
pip install deepproblog
```
## Test
To make sure your installation works, install pytest
```
pip install pytest
````
and run
```
python -m deepproblog test
```
## Requirements
DeepProbLog has the following requirements:
* Python > 3.9
* [ProbLog](https://dtai.cs.kuleuven.be/problog/)
* [PySDD](https://pysdd.readthedocs.io/en/latest/)
* [PyTorch](https://pytorch.org/)
* [TorchVision](https://pytorch.org/vision/stable/index.html)
## Approximate Inference
To use Approximate Inference, we have the followign additional requirements
* [PySwip](https://github.com/ML-KULeuven/pyswip)
- Use `pip install git+https://github.com/ML-KULeuven/pyswip`
* [SWI-Prolog < 9.0.0](https://www.swi-prolog.org/)
The latter can be installed on Ubuntu with the following commands:
```
sudo apt-add-repository ppa:swi-prolog/stable
sudo apt install swi-prolog=8.4* swi-prolog-nox=8.4* swi-prolog-x=8.4*
```
## Experiments
The experiments are presented in the papers are available in the [src/deepproblog/examples](src/deepproblog/examples) directory.
