MarsSeed [1] filed a deletion request for python2-sncosmo-doc [2]: I think this Python 2 based build of SNCosmo's documentation is unneded. Also it is broken because of the missing dependencies. Astronomy and cosmology Python packages were forced to move exclusively to Python 3 because of the loss of HDF5 support after 2019. So SNCosmo itself does no longer support Python 2.
