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. A large number of pre-trained models
3. Carefully designed APIs that greatly reduce the implementation complexity
4. Community supports

Installation

GluonCV supports Python 2.7/3.5 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
pip install -U --pre mxnet -f https://dist.mxnet.io/python/mkl
# if cuda 10.1 is installed
pip install -U --pre mxnet -f https://dist.mxnet.io/python/cu100mkl

The latest stable version of GluonCV is 0.7 and depends on mxnet >= 1.4.0

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
pip install -U --pre mxnet -f https://dist.mxnet.io/python/mkl
# if cuda 10.1 is installed
pip install -U --pre mxnet -f https://dist.mxnet.io/python/cu100mkl

There are multiple versions of MXNet pre-built package available. Please refer to mxnet packages if you need more details about MXNet versions.
