    Description

    Add-On Required: This feature requires the MATLAB Coder Support Package for PyTorch and LiteRT Models add-on.

    You can use PyTorchExportedProgram objects to execute the model or to generate code in MATLAB® or Simulink®.

    Creation

    Create a PyTorchExportedProgram object by using the loadPyTorchExportedProgram function.

    Properties

    Suppose that you have a PyTorch ExportedProgram model named siso.pt2 that takes one input and returns one output. Create a PyTorchExportedProgram object. 

    myModel = loadPyTorchExportedProgram("siso.pt2")
    Loading the model. This may take a few minutes.

    myModel = 
  PyTorchExportedProgram contained in siso.pt2:
