I’m new to pyMC3 and am still struggling to make sense of the API, with that said, my issue appears to be a dependency issue with multiprocessing I’m attempting to make a mixture model, specifying each distribution separately and then assigning them to comp_dists kwarg of Mixture() as a list. See …

AttributeError: Can't pickle local object 'Mixture._comp_dist_random_wrapper.<locals>.wrapped_random'

I’m not sure, actually. I ended up just using the cores= kwarg and otherwise running it on a Linux platform.
