inference_from_dicts() got an unexpected keyword argument "max_processes"

I received this error with finder.get_answers() from the tutorial.

This was from the version installed with git clone.

Issue was cause with an older version of farm. I needed to pip uninstall farm and reinstall farm-haystack with git clone.
