This repository contains code to reproduce the key findings of our path integral approach to prevent catastrophic forgetting in continual learning.

We have tested this maintenance release (v1.1) with the following configuration:

• Python 3.5.2
• Jupyter 4.4.0
• Tensorflow 1.10
• Keras 2.2.2

Kudos to Mitra (https://github.com/MitraDarja) for making our code conform with Keras 2.2.2!

For the original release (v1.0) we used the following configuration of the libraries which were available at the time:

• Python 3.5.2
• Jupyter 4.3.0
• Tensorflow 1.2.1
• Keras 2.0.5

To revert to such a environment we suggest using virtualenv (https://virtualenv.pypa.io):

virtualenv -p python3 env
source env/bin/activate
pip3 install -vI keras==2.0.5
pip3 install jupyter matplotlib numpy tensorflow-gpu tqdm seaborn
