Both problems should be solved by using the import guard and putting everything in a main function called within the guard: Thanks for contributing an answer to Stack Overflow! I guess the only solution currently is to leave the model as purely a keras model, and move the methods for data preprocessing outside of the model.

You definitely can serialize a weakref, and you can serialize a dict and a list.Basically, it matters what the objects contain. You must use import guards when using multiprocessing in 'spawn' mode, and failing to do so does some weird things.

In particular: The fork-emulation done in spawn mode will try to serialize some of the main module's state for transfer to the child process to initialize the child similarly; multiprocessing.Process itself is not picklable as of Python 3.7 (though there's a patch pending to fix it), so you definitely don't want to have it anywhere it might get pickled. The code below works but if you replaced keras with tf.keras, there will be an error: We are trying to execute this piece of code using the multiprocessing module: And we run into the below error in Python 3.8 that is not seen in Python 3.6: Is there something in the way the process is started or the arguments supplied that needs to be changed or checked? I'm trying several ways because I'm stuck with capacity limitations during software deployment. 1 By not using the guards, the child process's import of the main module does all the things the main module does, including launching a child (which itself launches a child, and so on, ad infinitum).

Unable to change colour of a specified cell of a frame in tkinter? The original object can be retrieved by calling the reference object if the referent is still alive; if the referent is no longer alive, calling the reference object will cause None to be returned. I have tested it and it works.

I suspect the code above would work without changing the spawn method if you set the environment variable MUJOCO_GL=osmesa when launching your interpreter. Module objects are now weakref 'able. This post sheds light on a common pitfall of the Python multiprocessing module: spending too much time serializing and deserializing data before shuttling it to/from your child processes.I gave a talk on this blog post at the Boston Python User Group in August 2018 In particular: The fork-emulation done in spawn mode will try to serialize some of the main module's state for transfer to the child process to initialize the child similarly; multiprocessing.Process itself is not picklable as of Python 3.7 (though there's a patch pending to fix it), so you definitely don't want to have it anywhere it might get pickled. def test_tf(): Traceback (most recent call last):
