hypermapper: pickle related error

I’m trying to run the demo examples (through anaconda / jupyter) but am hitting some pickle related issues **AttributeError: Can't pickle local object 'local_search.<locals>.parallel_optimization_function'** I am not familiar with the issue - I tried googling about this but could not find a satisfactory answer. Could you please tell me if this is an error specific to my system / setup or if this is a known issue?

Thank you!
