It seems that increasing the scope of a keras model (including extra preprocessing steps, etc) and throwing everything into a PythonModel isn't supported. 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. And other files scalar_in and scalar_out do not save in a specific folder. Parallel(n_jobs=8)(delayed(test)(i) for i in range(10)) #this works as intended Moving forward, tf.keras should be replacing keras and therefore tf.keras should also be pickleable.
