Reti preaddestrate da piattaforme esterne

Importare reti preaddestrate da piattaforme esterne di Deep Learning

Importare reti neurali da TensorFlow™ 2, TensorFlow-Keras, PyTorch^®, il formato di modello ONNX™ (Open Neural Network Exchange) e Caffe. Per ulteriori informazioni, vedere Reti neurali profonde preaddestrate e Interoperability Between Deep Learning Toolbox, TensorFlow, PyTorch, and ONNX.

Per eseguire le funzioni di importazione in Deep Learning Toolbox™ è necessario disporre dei pacchetti di supporto. Se il pacchetto di supporto non è installato, ciascuna funzione fornisce un link per il download del pacchetto di supporto corrispondente nell'Add-On Explorer. Si consiglia di scaricare il pacchetto di supporto nella posizione predefinita per la versione MATLAB^® in uso. È inoltre possibile scaricare direttamente i pacchetti di supporto dai seguenti link.

La funzione importNetworkFromONNX richiede Deep Learning Toolbox Converter for ONNX Model Format. Per scaricare il pacchetto di supporto, andare a https://www.mathworks.com/matlabcentral/fileexchange/67296-deep-learning-toolbox-converter-for-onnx-model-format.
La funzione importNetworkFromPyTorch richiede il convertitore Deep Learning Toolbox per i modelli PyTorch. Per scaricare il pacchetto di supporto, andare a https://www.mathworks.com/matlabcentral/fileexchange/111925-deep-learning-toolbox-converter-for-pytorch-models.
La funzione importNetworkFromTensorFlow richiede il convertitore Deep Learning Toolbox per i modelli TensorFlow. Per scaricare il pacchetto di supporto, andare a https://www.mathworks.com/matlabcentral/fileexchange/64649-deep-learning-toolbox-converter-for-tensorflow-models.
