I was trying to run the quickstart circuit for Borealis locally and got this error:
ImportError: cannot import name ‘is_ptype’ from ‘blackbird.listener’ (~/blackbird/listener.py)
I commented out code requiring is_ptype for now, but I think this is what is causing my other error (_contains_ in borealis compiler has a string?).
I am running the latest version of strawberryfields, any suggestions about how to fix?
