so this fails:

  File "/home/desika.narayanan/miniconda3/envs/pd4env/lib/python3.6/site-packages/hyperion/model/model.py", line 12, in <module>
    from astropy.extern import six
ImportError: cannot import name 'six'

easy fix in code to just do an import six but i don't know where to have hyperion automatically download six and install it in both the source and conda package in order to issue a pull request.

Yup, encountered the same when importing aplpy. Had to manually modify several packages to import six directly

same! (with importing aplpy)

See related issue (and the fix that worked for me) here: aplpy/aplpy#443

astropy.extern no longer packages six with it. sncosmo v2.1.0 removed
all references to six:

    v2.1.0 (2020-02-25)
    ===================

    - Add ZTF transmission functions

    - Bugfixes

      - Corrected pyproject.toml; should help cases where the wrong numpy
        version was being installed.

      - Remove all references to the six package

      - Fix accidental mutation of ``bounds`` inputs in ``fit_lc`` and
        ``mcmc_lc``.

This upgrade should resolve this issue

this issue isn't updated in the conda installation - would it be possible to rebuild the conda install quickly?

Seconding the conda package update request. I'm still getting the same error from a version installed today via conda.
