Pipetask - QuantumGraph issues

Tags: #<Tag:0x00007fdd78a5f048>

Hi all,

I am trying to debug a notebook that should be reproducing a file that runs successfully when run from the main RSP Terminal.

My issue is when running the following code line:

pipetask run -b /project/gmegias/aos/lsst_stack/perturbations/phosimData -i refcats,LSSTComCam/raw/all,LSSTComCam/calib --instrument lsst.obs.lsst.LsstComCam --register-dataset-types --output-run ts_phosim_1151 -p comcamPipeline.yaml -d "exposure IN (4021114101151, 4021114101152)" -j 2

I tried running this line of code from the LSP terminal to see if I could get an insight on what was going on, but the following error prompts up:

    py.warnings WARN: /opt/lsst/software/stack/stack/miniconda3-py38_4.9.2-0.6.0/Linux64/ctrl_mpexec/21.0.0-33-g1dfc228+1cc4008e43/python/lsst/ctrl/mpexec/cli/script/qgraph.py:145: UserWarning: QuantumGraph is empty

If anyone has any idea of what could I be doing wrong, I would appreciate a lot your support!

Here is a discussion on empty quantum graphs that might help you.

Can you post a link to your comcamPipeline.yaml ?

Can you also run butler query-datasets to check that those exposures really are present in that LSSTComCam/raw/all collection?

I can only see exposures 4021123101151 and 4021123101152 in LSSTComCam/raw/all collection .

If this is phosim on-sky data then not running butler define-visits is a possibility (that is covered in the FAQ).

I think that was the issue. The problem is now solved. See follow-up issue in:
