ReZero-examples

This repo contains examples demonstrating the power of the ReZero architecture, see the paper.

The official ReZero repo is here.

• ReZero speeds up superconvergence

• ReZNet - Faster ResNet training via ReZero

Final valid errors: Vanilla - 7.74. FixUp - 7.5. ReZero - 6.38, see .

• Training 128 layer ReZero Transformer on WikiText-2 language modeling
• Training 10,000 layer ReZero fully connected network on CIFAR-10

Contribute

If you find ReZero or a similar architecture improves the performance of your application, you are invited to share a demonstration here.

Install

To install ReZero via pip use pip install rezero

Usage

We provide custom ReZero Transformer layers (RZTX).

For example, this will create a Transformer encoder:

import torch
import torch.nn as nn
from rezero.transformer import RZTXEncoderLayer

encoder_layer = RZTXEncoderLayer(d_model=512, nhead=8)
transformer_encoder = nn.TransformerEncoder(encoder_layer, num_layers=6)
src = torch.rand(10, 32, 512)
out = transformer_encoder(src)
