Trouble installing and running healsparse 1.1.1 in DM v19 environment

[heather999]

This is ultimately impacting my ability to install and run supreme, but the problem seems to be due to healsparse. I grabbed lsstsqre/centos:7-stack-lsst_distrib-v19_0_0 and in the container I do:

source loadLSST.bash
pip install healsparse
python -c "import healsparse"

and I end up with an error:

ImportError: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /opt/lsst/software/stack/python/miniconda3-4.7.10/envs/lsst-scipipe-4d7b902/lib/python3.7/site-packages/scipy/sparse/_sparsetools.cpython-37m-x86_64-linux-gnu.so)

I see you're testing supreme with DM v19... though looking at the healsparse GH workflow, I think it's being testing with scipy 1.4.1 which isn't in DM v19 (maybe I'm not looking at all the workflow variants). If I again start with the DM v19 docker image and install scipy 1.4.1, then healsparse, I still get a similar, though slightly different, error:

ImportError: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /opt/lsst/software/stack/python/miniconda3-4.7.10/envs/lsst-scipipe-4d7b902/lib/python3.7/site-packages/scipy/_lib/_uarray/_uarray.cpython-37m-x86_64-linux-gnu.so)

Any ideas what might be going wrong?

actually.. I think this may be an issue with healpy as the error also occurs if I do:
python -c "import healpy"
I have healpy 1.13.0

Poking into the most recent github action for supreme
I noticed it used healpy==1.10.3 Constraining the install to that version appears to work, and then I can successfully install healsparse and supreme. :)

Ah, I found the issue. If you're installing healsparse with the Rubin stack, then you must to first do setup lsst_distrib before pip install healsparse in order to match all the correct dependencies.
