Hello yfxcore,
You can indeed import Pytorch and TensorFlow models into MATLAB/Simulink. To do so for Pytorch, you can use the function called 'importNetworkFromPyTorch'. For additional information, consult the following documentation:
The function importNetworkFromPyTorch(model file) allows you to import a pretrained and traced Pytorch model from the specified model file. This function returns the network as an uninitialized ‘dlnetwork’ object. To use importNetworkFromPyTorch, you need the Deep Learning Toolbox Converter for Pytorch Models support package.
This dlnetworks object can be converted into a Simulink model using predict block. For more information on predict block follow the following documentation,
Also please refer to the following guidelines to ask questions on MATLAB answer and get better response,
Hope this helps.
