Vortrainierte Netze von externen Plattformen

Importieren von vortrainierten Netzen von externen Deep-Learning-Plattformen

Importieren Sie neuronale Netze von TensorFlow™ 2, TensorFlow-Keras, PyTorch^®, dem ONNX™-Modellformat (Open Neural Network Exchange) und Caffe. Weitere Informationen finden Sie unter Pretrained Deep Neural Networks und Interoperability Between Deep Learning Toolbox, TensorFlow, PyTorch, and ONNX.

Sie müssen über Support-Paket verfügen, um die Importfunktionen in Deep Learning Toolbox™ ausführen zu können. Wenn das Support-Paket nicht installiert ist, bietet jede Funktion einen Download-Link zum entsprechenden Support Package im Add-On Explorer. Es wird empfohlen, das Support-Paket an den Standardspeicherort der von Ihnen verwendete MATLAB^®-Version herunterzuladen. Sie können die Support-Pakete auch direkt über die folgenden Links herunterladen.

Die Funktion importNetworkFromONNX erfordert den Deep Learning Toolbox-Konverter für das ONNX-Modellformat. Sie können das Support-Paket unter https://www.mathworks.com/matlabcentral/fileexchange/67296-deep-learning-toolbox-converter-for-onnx-model-format herunterladen.
Die Funktion importNetworkFromPyTorch erfordert den Deep Learning Toolbox-Konverter für PyTorch-Modelle. Sie können das Support-Paket unter https://www.mathworks.com/matlabcentral/fileexchange/111925-deep-learning-toolbox-converter-for-pytorch-models herunterladen.
Die Funktion importNetworkFromTensorFlow erfordert den Deep Learning Toolbox Konverter für TensorFlow-Modelle. Sie können das Support-Paket unter https://www.mathworks.com/matlabcentral/fileexchange/64649-deep-learning-toolbox-converter-for-tensorflow-models herunterladen.
