PyRetri

Introduction

PyRetri is an open source deep learning-based image retrieval toolbox based on PyTorch.

Major features

• Modular Design

  We decompose the deep learning-based image retrieval into several stages and one can easily construct a image retrieval pipeline by combining different modules.

• Flexible Loading

  The toolbox is able to adapt to load several types of model parameters, including parameters with the same keys and shape, parameters with different keys, and parameters with the same keys but different shapes.

• Support of Multiple Methods

  The toolbox directly supports popluar methods designed fot deep learning-based image retrieval.

• Combinations Search Tool

  We provide the pipeline combinations search scripts to help users to find possible combinations of approaches with various hyper-parameters.
