A single stage object detector toolbox based on PyTorch

Introduction

vedadet is a single stage object detector toolbox based on PyTorch.

Features

• Modular Design

  We re-design MMDetection based on our taste and needs. Specifically, we decompose detector into four parts: data pipeline, model, postprocessing and criterion which make it easy to convert PyTorch model into TensorRT engine and deploy it on NVIDIA devices such as Tesla V100, Jetson Nano and Jetson AGX Xavier, etc.

• Support of several popular single stage detector

  The toolbox supports several popular single stage detector out of the box, e.g. RetinaNet, FCOS, etc.

• Friendly to TensorRT

  Detectors can be easily converted to TensorRT engine.

• Easy to deploy

  It's simple to deploy the model accelerate by TensorRT on NVIDIA devices through Python front-end or C++ front-end.
