I have never coded in Rudy (I have no knowledge about it). And I don’t think Rudy is part of the environment (I prefer this word to language) where we can manipulate pytorch/tensorflow models (js, C++, …)
In this kind of case you can deploy your model in a python (or compatible) environment, for example a Django/Flask (torch) or nodejs (torch-js) API… And query it from Rudy
