No backend matches the criteria

[catskillsresearch]

After installing qiskit version 0.16.4 with pip on Ubuntu in Python 3.8.5, and running tutorial 1 notebook, for this command:

initialize = []
success_condition = {}
allowed_gates = {'0': {'NOT': 3}, '1': {}, 'both': {}}
vi = [[1], False, False]
qubit_names = {'0':'the only bit', '1':None}
engine.run_game(initialize, success_condition, allowed_gates, vi, qubit_names)

I get error
