Mammoth - An Extendible (General) Continual Learning Framework for Pytorch

Official repository of:

Mammoth is a framework for continual learning research. With more than 40 methods and 20 datasets, it includes the most complete list competitors and benchmarks for research purposes.

The core idea of Mammoth is that it is designed to be modular, easy to extend, and - most importantly - easy to debug. Ideally, all the code necessary to run the experiments is included in the repository, without needing to check out other repositories or install additional packages.

With Mammoth, nothing is set in stone. You can easily add new models, datasets, training strategies, or functionalities.

All the models included in mammoth are verified against the original papers (or subsequent relevant papers) to reproduce their original results.

Documentation

Setup

  • Install with pip install -r requirements.txt. NOTE: Pytorch version >= 2.1.0 is required for scaled_dot_product_attention (see: Lightning-AI/litgpt#763). If you cannot support this requirement, uncomment the lines 136-139 under scaled_dot_product_attention in backbone/vit.py.
  • Use ./utils/main.py to run experiments.
  • New models can be added to the models/ folder.
  • New datasets can be added to the datasets/ folder.

Update roadmap

All the code is under active development. Here are some of the features we are working on:

  • Configurations for datasets: Currently, each dataset represents a specific configuration (e.g., number of tasks, data augmentations, backbone, etc.). This makes adding a new setting a bit cumbersome. We are working on a more flexible way to define configurations, while leaving the current system as a default for retro-compatibility.
  • New models: We are working on adding new models to the repository.
  • New training modalities: We will introduce new CL training regimes, such as training with noisy labels, regression, segmentation, detection, etc.
  • Openly accessible result dashboard: We are working on a dashboard to visualize the results of all the models in both their respective settings (to prove their reproducibility) and in a general setting (to compare them). This may take some time, since compute is not free.

All the new additions will try to preserve the current structure of the repository, making it easy to add new functionalities with a simple merge.
