hivemind: decentralized deep learning in PyTorch

Hivemind is a PyTorch library to train large neural networks across the Internet. Imagine training one huge Transformer model on thousands of computers from different universities, companies, and volunteers.

Key Features

• Train neural networks of arbitrary size: parts of their layers are distributed across the participants
• Run distributed training without master node: Distributed Hash Table allows to connect computers in a decentralized network
• Fault-tolerant backpropagation: forward and backward passes succeed even if some nodes are unresponsive or take too long to respond

To learn more about the idea behind this library and its components, see https://learning-at-home.github.io or read the NeurIPS 2020 paper

Documentation

• Quickstart tutorial: install hivemind, set up a server and train experts
  
• Documentation & guides: learning-at-home.readthedocs.io

Contributing

Hivemind is currently at the active development stage, and we welcome all contributions from bug fixes and documentation improvements to entirely new features.
