The reason why I'm even converting it to the a pyfunc flavor is because i want to override the PREDICT method and output something custom - instead of the probabilities, i want to output the class with the highest probability and serve it using MLFLOW model serving. Reply to this email directly, view it on GitHub Sublime Text Thus if a `multiprocessing.Process` instance holds a reference to a started `multiprocessing.Process` instance then it holds a weak reference (point 2), so starting it will fail since it will serialise (point 1) the weak reference and weak references are not serialisable: ``` import multiprocessing if __name__ == '__main__': Setting up a dictionary with 1 list and a list of lists.
