Meq tree fails when running set_model during crosscal #1571

Closed ianjarog closed 4 months ago

Hi all,

Does anybody know what causes the attached errors? Looks like it failed at the set_model stage, when trying to import the primary calibrator's local sky model into the MODEL_DATA column.

Hi @ianjarog thanks for reporting this issue. It is related to #1316. Try reducing tile_size. Please confirm if the same error persist with a re-run, and after changing the params.

@Athanaseus Thanks, setting it to 8 solved it. I am closing this
