Notice 1

If you have not visited the landing page of at https://github.com/TexasInstruments/edgeai, please do so before attempting to use this repository. We skip most of the introduction in this repository.
This repository is located in Github at: https://github.com/TexasInstruments/edgeai-torchvision

Notice 2

The scripts in this repository use Model Optimization Tools in edgeai-modeloptimization. It is installed during pip install using requirements.txt file - so there is no need to clone it, unless you want to modify it.

<hr>

This repository is an extension of the popular mmdetection open source repository for object detection training. While mmdetection focuses on a wide variety of models, typically at high complexity, we focus on models that are optimized for speed and accuracy so that they run efficiently on embedded devices. For this purpose, we have added a set of embedded friendly model configurations and scripts - please see the Usage for more information.

If the accuracy degradation with Post Training Quantization (PTQ) is higher than expected, this repository provides instructions and functionality required to do Quantization Aware Training (QAT).

Release Notes

See notes about recent changes/updates in this repository in release notes

Installation

These installation instructions were tested using Miniconda Python 3.7 on a Linux Machine with Ubuntu 18.04 OS.

Make sure that your Python version is indeed 3.7 or higher by typing:<br>

python --version

Please clone and install EdgeAI-Torchvision as this repository uses several components from there - especially to define low complexity models and to do Quantization Aware Training (QAT) or Calibration.

After that, install this repository by running ./setup.sh

After installation, a python package called "mmdet" will be listed if you do pip list

In order to use a local folder as a repository, your PYTHONPATH must start with a : or a .: Please add the following to your .bashrc startup file for bash (assuming you are using bash shell).

export PYTHONPATH=:$PYTHONPATH

Make sure to close your current terminal or start a new one for the change in .bashrc to take effect or one can do source ~/.bashrc after the update.

Get Started

Please see Usage for training and testing with this repository.

Object Detection Model Zoo

Complexity and Accuracy report of several trained models is available at the Detection Model Zoo

Quantization

This tutorial explains more about quantization and how to do Quantization Aware Training (QAT) of detection models.

ONNX & Prototxt Export

Export of ONNX model (.onnx) and additional meta information (.prototxt) is supported. The .prototxt contains meta information specified by TIDL for object detectors.

The export of meta information is now supported for SSD and RetinaNet detectors.

For more information please see Usage

Advanced documentation

Kindly take time to read through the documentation of the original mmdetection before attempting to use extensions added this repository.

The setup script setup.sh in this repository has the commonly used settings. If your CUDA version is different or your Python version is different or if you have some missing packages in your system, this script can fail. In those scenarios, please refer to installation instructions for original mmdetection for detailed installation instructions.

Also see documentation of MMDetection for the basic usage of original mmdetection.

Acknowledgement

This is an open source project that is contributed by researchers and engineers from various colleges and companies. We appreciate all the contributors who implement their methods or add new features, as well as users who give valuable feedbacks.

We wish that the toolbox and benchmark could serve the growing research community by providing a flexible toolkit to train existing detectors and also to develop their own new detectors.
