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__': How to use the tensors inside a Keras custom loss function?

Pickling successful. The technical post webpages of this site follow the CC BY-SA 4.0 protocol. This works now. I've also run into this issue. I guess a quick fix would just be to replace all the existing code with tf.keras to just keras but seeing as keras support will be discontinued and absorbed by Tensorflow 2.0, I think this should be fixed. Menu Multiprocessing.Pool() - Stuck in a Pickle 16 Jun 2018 on Python Intro.

While it works great using mlflow.keras.log_model, I cant convert it to a pyfunc flavor. It was due to that an object had a running or exited Process as a variable and it was starting another Process using that object.
