Errors when using quilc #33

Open lauracaune opened 2 years ago

lauracaune commented 2 years ago

I was trying to use quilc with Rigetti's Qiskit provider and got the error as in the first screenshot. As suggested by Rigetti, I fixed it following the instructions from this page - https://qiskit-rigetti.readthedocs.io/en/latest/. However, now I get a new error as in the second screenshot. I'm not sure if this is an error in my code or on your side. Could you please help with this? Thank you!

Hi @lauracaune -

Would you be able to also share:

Thanks!

Hi @nilslice,

My apologies for the late reply. This is the program I am trying to run: OPENQASM 2.0; include "qelib1.inc"; qreg q[1]; creg c[1]; x q[0]; measure q[0] -> c[0];

I'm using Aspen-11-qvm as the backend and doing the command run on it. I don't remember anymore as this was a while ago, but I think I isntalled quilc using this - https://qcs.rigetti.com/sdk-downloads. Weirdly, this is only an issue from my local machine. When I run the same code on the Jupyterlab provided by Rigetti everything runs smoothly.

Thank you :)

@lauracaune I'm able to run that program through quilc version 1.26.0 locally. Can you check what version you're using? If you're using a quilc binary from the downloads page, can you instead try running it via Docker as indicated here?

Hi @dbanty, I've been running quilc via Docker. I thought this means it's the latest version? If not, I'm not sure how to check the version via Docker? I also tried using a different program and got the same error.

I don't think the image will be automatically updated, so if you pulled it a while ago it could be stale? You can do a docker pull rigetti/quilc to see if there are updates. A docker run rigetti/quilc --version will print out the current version.

When you say "another program" do you mean another OPENQASM 2.0 program? Can you try compiling a simple Quil program like DECLARE ro BIT; MEASURE 0 ro to see if it can handle that? That will at least tell us if the quilc image is completely broken.
