How do I export a neural network from MATLAB?

I have a neural network which I trained using MATLAB. I want to export the network so I can use it with other frameworks, for example PyTorch. How do I do that?

You can export a Deep Learning Toolbox network or layer graph to TensorFlow and ONNX using the "exportNetworkToTensorFlow" and "exportONNXNetwork" functions, respectively.  For more information about exporting networks to external deep learning platforms, please see the following documentation page:

https://uk.mathworks.com/help/deeplearning/export-deep-neural-networks.html

If you want to export you network to use in another framework, such as PyTorch, you should first export your network using the "exportONNXNetwork" function then, this ONNX model can then be imported into other deep learning frameworks that support ONNX model import.

should i compile to full caffe in c++ ?

The exportONNXNetwork function in Deep Learning Toolbox Converter for ONNX Model Format allows one to export a trained deep learning network to the ONNX™ (Open Neural Network Exchange) model format. The ONNX model can then be imported into other deep learning frameworks that support ONNX model import.

To use the network with TensorFlow, use the exportNetworkToTensorFlow function that is part of the Deep Learning Toolbox Converter for TensorFlow Models.

still i have no success to import it to c++ from onnx there are many issues of compilation

after testing onnx i found that the output of convolutions is not the same as in matlab .
