Deep Learning Import and Export

Import networks from and export networks to external deep learning platforms

Import networks and network architectures from TensorFlow™-Keras, TensorFlow 2, Caffe, and the ONNX™ (Open Neural Network Exchange) model format. You can also export a trained Deep Learning Toolbox™ network to the ONNX model format.

Topics

Assemble Network from Pretrained Keras Layers

This example shows how to import the layers from a pretrained Keras network, replace the unsupported layers with custom layers, and assemble the layers into a network ready for prediction.

Replace Unsupported Keras Layer with Function Layer

This example shows how to import the layers from a pretrained Keras network, replace the unsupported layers with function layers, and assemble the layers into a network ready for prediction.

Deploy Imported Network with MATLAB Compiler

Import Keras and ONNX pretrained networks and deploy the networks using MATLAB^® Compiler™.
