Python multiprocessing - When is a referenced object shared? 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 Scape gtag/jquery variables with BeautifulSoup? We'll fix the documentation in the near term, and think about how to better address the usability in long term.

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). Get elements of list only with a certain distance between items? Moving forward, tf.keras should be replacing keras and therefore tf.keras should also be pickleable. See Note [Sharing CUDA tensors] Appending array rows to .txt file in Python 3, Reading two columns of numbers from a text file in python. Customize search results with 150 apps alongside web results. If I am performing data preprocessing on training data, is it necessary to perform the same on test data? Alternatively, I've tried mlflow.keras.save_model and included a custom_objects param with preprocess functions, however the objects aren't restored with mlflow.keras.load_model(), pickle.dump(model,pickle_out) Sign in pathos pip install pathos code Have a question about this project? This problem is likely a side-effect of a bigger bug in your application. 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 best solution is to do all feature extracting for one score on one processor and do the parsing of the file, etc. **Other comments** 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.
