Keras APIs # Update 2019.03 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 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.

[Solved] Unable to detect user location in Google Maps URL launched in WebView from Flutter app. 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. do i need to use exactly same attribute names to properties in custom preprocessing class which inherit scikit learn BaseEstimator?
