In R2022b we introduced the Deep Learning Toolbox Converter for PyTorch Models support package. This initial release supports importing image classification models. Support for other model types will be added in future releases. Use the function importNetworkFromPyTorch to import a PyTorch model. Make sure that the PyTorch model that you are importing is pretrained and traced.
