PyNeuraLogic is a framework built on top of NeuraLogic which combines relational and deep learning.

---

General

Supported backends (WIP):

• PyTorch Geometric (PyG)
• DyNet
• Deep Graph Library (DGL)

Getting started

Prerequisites

To use PyNeuraLogic, you need to have installed the following prerequisites.

Python >= 3.7
Java 1.8

Installation

To install PyNeuraLogic's latest release from the PyPI repository, use the following command.

$ pip install neuralogic

How to use

None of the following backends are included in PyNeuraLogic's installation. You have to install the ones that you are planning to utilize manually.

With PyTorch Geometric

With DyNet

import dynet as dy
from neuralogic import data
from neuralogic.dynet import NeuraLogicLayer

dataset = data.XOR  # Use one of the default datasets in the project in the/datasets/ folder

layer = NeuraLogicLayer(dataset.weights)  # Create an instance of NeuraLogicLayer with weights from the dataset
trainer = dy.AdamTrainer(layer.model, alpha=0.001)

for sample in dataset.samples:  # Learn on each sample
    dy.renew_cg(immediate_compute=False, check_validity=False)
    label = dy.scalarInput(sample.target)

    graph_output = layer.build_sample(sample)

    loss = dy.squared_distance(graph_output, label)
    loss.forward()
    loss.backward()
    trainer.update()

With Deep Graph Library
