Lsst-dev “shared stack” updated for DM-21746, DM-21899, DM-22035

The “shared stack” on lsst-dev has been refreshed to reflect the changes to the Conda environment made on DM-21746, DM-21899 and DM-22035. That means that:

  • Pytest is now drawn from the Conda environment, rather than a EUPS product;
  • Pyarrow is included in the Conda environment;
  • Astropy has been updated to version 3.2.3.

The new stack can be found at /software/lsstsw/stack_20191101. It currently contains weekly w_2019_43; it will be updated with new weeklies as they become available. It also contains the following “bonus” packages:

  • cx_Oracle (from Conda)
  • Git LFS (declared using EUPS)
  • dask (from Conda)
  • ipdb (from Conda -c conda-forge )

Please follow-up to this post with any requests for further packages to be added.

The old stack, providing weeklies w_2019_38 through w_2019_42 and daily d_2019_09_30, will remain available at /software/lsstsw/stack_20191001 for the time being, but won’t be regularly updated.

/software/lsstsw/stack will always be a symlink to the latest stack.

Refer to the Developer Guide for further details.
