Gluon CV Toolkit

| Installation | Documentation | Tutorials |

GluonCV provides implementations of the state-of-the-art (SOTA) deep learning models in computer vision.

It is designed for engineers, researchers, and students to fast prototype products and research ideas based on these models. This toolkit offers four main features:

1. Training scripts to reproduce SOTA results reported in research papers
2. Supports both PyTorch and MXNet
3. A large number of pre-trained models
4. Carefully designed APIs that greatly reduce the implementation complexity
5. Community supports

Please also checkout AutoGluon if you have image classification or object detection needs. We have built the MultimodalPredictor with an improved model zoo, including TIMM, Huggingface, MMDetection and more. With just a few lines of code, you can train and deploy high accuracy computer vision models for your application.

Supported Applications

Installation

GluonCV is built on top of MXNet and PyTorch. Depending on the individual model implementation(check model zoo for the complete list), you will need to install either one of the deep learning framework. Of course you can always install both for the best coverage.

Please also check installation guide for a comprehensive guide to help you choose the right installation command for your environment.

Installation (MXNet)

GluonCV supports Python 3.6 or later. The easiest way to install is via pip.

Stable Release

The following commands install the stable version of GluonCV and MXNet:

pip install gluoncv --upgrade
# native
pip install -U --pre mxnet -f https://dist.mxnet.io/python/mkl
# cuda 10.2
pip install -U --pre mxnet -f https://dist.mxnet.io/python/cu102mkl

The latest stable version of GluonCV is 0.8 and we recommend mxnet 1.6.0/1.7.0

Nightly Release

You may get access to latest features and bug fixes with the following commands which install the nightly build of GluonCV and MXNet:

pip install gluoncv --pre --upgrade
