Implementation of Graph Transformer in Pytorch, for potential use in replicating Alphafold2

Last update: Dec 28, 2022

Overview

Graph Transformer - Pytorch

Implementation of Graph Transformer in Pytorch, for potential use in replicating Alphafold2. This was recently used by both Costa et al and Bakers lab for transforming MSA and pair-wise embedding into 3d coordinates.

Todo

add rotary embeddings for injecting adjacency information

Install

$ pip install graph-transformer-pytorch

Usage

import torch
from graph_transformer_pytorch import GraphTransformer

model = GraphTransformer(
    dim = 256,
    depth = 6,
    edge_dim = 512,             # optional - if left out, edge dimensions is assumed to be the same as the node dimensions above
    with_feedforwards = True,   # whether to add a feedforward after each attention layer, suggested by literature to be needed
    gated_residual = True       # to use the gated residual to prevent over-smoothing
)

nodes = torch.randn(1, 128, 256)
edges = torch.randn(1, 128, 128, 512)
mask = torch.ones(1, 128).bool()

nodes, edges = model(nodes, edges, mask = mask)

nodes.shape # (1, 128, 256) - project to R^3 for coordinates

Comments

fix mask bug in batch setting

The original implementation accidentally assumes batch size 1 here, and the mask's batch dimension (1) is automatically broadcast to the # of heads. If batch size is greater than 1, we have to handle that explicitly by copying it once for each head.
