Hello, I am currently going through the tutorial on PyTorch and noisy devices at (https://)[PyTorch and noisy devices — PennyLane documentation ].
When I run the following code to run on the Rigetti QVM:
dev = qml.device(“rigetti.qvm”, device=‘Aspen-8’, noisy=True)
I receive the following:
DeviceError: Device does not exist. Make sure the required plugin is installed.
All required dependencies/plugins have been installed. How can this issue be resolved? Thank you in advance!
Hi @gopalm-ai,
Could you please post the output of qml.about() and your full error traceback?
It is possible that the pennylane-rigetti plugin was installed in a different environment to the one you’re currently using. You could try installing it in the current environment using pip install pennylane-rigetti.
If it says it’s already installed you might need to try creating a new environment. This may be more clear once we can see the output of qml.about() and your full error traceback. I hope this can help you debug in the meantime.
Here is the latest error I receive:
QCSHTTPStatusError: QCS API call GET https://api.qcs.rigetti.com/v1/quantumProcessors/Aspen-8/instructionSetArchitecture failed with status 403: {“code”:“unauthorized”,“message”:“User unauthorized”,“requestId”:“aeb8875f-d9a3-4779-bf3a-7d2a91630582”}
