Trying to Follow the tutorial steps of article:
[ https://pennylane.ai/qml/demos/tutorial_gbs.html ]
My qml packet version of pennylane (upgraded today via pip) is: 0.13.0
Error at statement:
dev = qml.device(“strawberryfields.gaussian”, wires=n_wires, cutoff_dim=cutoff)
Throws error message:
TypeError: init() got an unexpected keyword argument ‘cutoff_dim’
Could you please assist. Thanks in advance.

Hi @falbriard,
At first glance, it might be that you have an older version of Strawberry Fields (which performs the underlying GBS simulations) installed. Could you try upgrading strawberryfields and pennylane-sf via pip and see if the problem remains?
Dear colleagues. Thanks for the reply. The solution worked like a charm
by updating the package “pennylane-sf” and its dependency, the package “numba”. I’ve tested the code posted in the article and it worked OK.
