GalSim version too old for mp_context kwarg? #17

Open kadrlica opened 4 years ago

kadrlica commented 4 years ago

When trying to call imSim, I get the error:

I'm guessing that this is a newer addition to GalSim, and we may need to update the version of the DM stack to capture it.

I think the mp_context option was added in galsim v2.2. I would have thought that the v20 stack has that version or later. It's definitely in the more recent weeklies.

Yep, that's where I'm going with this. I started with w_2020_20 which has v2.2.3. Looks like the weekly is missing a sims build, so I'll try another. Using v20 would be nice.

Looking at Heather's comment here w_2020_24 seems like a good bet.

kadrlica commented 4 years ago

Ok, so indeed w_2020_24 works for GalSim. However, with this stack version EUPS complains about not being able to setup healpy when trying to build sims_ci_pipe, though the w_2020_24 env has healpy installed. I think this is keeping sims_ci_pipe from building in a consistent environment that can be used to run imsim. I'll keep looking for some consistent env.
