classiq synthesize error
Hello,
I am getting failed execution of
aqora test, when the classiq's synthesize function is called. Below is the minimal code that reproduces the issue, the error output and versions info.Code:
from classiq import *
@qfunc
def main(qbit: Output[QBit]):
allocate(1, qbit)
X(qbit)
test_qmod = create_model(main)
test_qprog = synthesize(test_qmod)Error output:
[1 FAIL] Evaluation error

To try and fix this, you can:
- Check the above error and try again
sys:1: RuntimeWarning: coroutine 'synthesize_async' was never awaitedVersions:
classiq 0.58.1>aqora -V
aqora 0.8.0
Python 3.10.11 (tags/v3.10.11:7d4cc5a, Apr 5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)]Could you please check?
Thanks a lot!

Hello @quantotto !
Thank you for bringing this to our attention! I understand you're experiencing issues with the synthesis function in Aqora notebooks.
I'd like to clarify that Aqora notebooks process cells asynchronously by design, which requires the use of async-compatible functions throughout your code. For your specific case, instead of
classiq.synthesis(test_qmod), you'll want to use await classiq.synthesis_async(test_qmod), which is specifically designed for this asynchronous environment.For a deeper understanding of how Python's
asyncio works in this context, I recommend reviewing this tutorial on the subject. This should help you better understand the underlying principles.Please don't hesitate to reach out if you need any further clarification or run into other questions during the competition. We're here to help ensure your success.

Thanks @quantotto for reporting! We will investigate

Hi @quantotto, thanks for looking at it.
Actually, I am not sure how this could be resolved either. But I can run it locally on my laptop without interruption. I guess it is because the aqora test has specific checking implementation?
Would you be able to help @julian ? Thanks!
