ONNX* is a representation format for deep learning models. ONNX allows AI developers easily transfer models between different frameworks that helps to choose the best combination for them. Today, PyTorch*, Caffe2*, Apache MXNet*, Microsoft Cognitive Toolkit* and other tools are developing ONNX support.

Listed models are built with operation set version 8. Models that are upgraded to higher operation set versions may not be supported.
Starting from the R4 release, the OpenVINO™ toolkit officially supports public Pytorch* models (from
torchvision 0.2.1 and
pretrainedmodels 0.7.4 packages) via ONNX conversion. The list of supported topologies is presented below:
|Package Name||Supported Models|
|Torchvision Models||alexnet, densenet121, densenet161, densenet169, densenet201, resnet101, resnet152, resnet18, resnet34, resnet50, vgg11, vgg13, vgg16, vgg19|
|Pretrained Models||alexnet, fbresnet152, resnet101, resnet152, resnet18, resnet34, resnet152, resnet18, resnet34, resnet50, resnext101_32x4d, resnext101_64x4d, vgg11|
Starting from the R5 release, the OpenVINO™ toolkit officially supports public PaddlePaddle* models via ONNX conversion. The list of supported topologies is presented below:

The Model Optimizer process assumes you have an ONNX model that was directly downloaded from a public repository or converted from any framework that supports exporting to the ONNX format.
To convert an ONNX* model:
mo.pyscript to simply convert a model with the path to the input model
There are no ONNX* specific parameters, so only framework-agnostic parameters are available to convert your model.
Refer to Supported Framework Layers for the list of supported standard layers.
