MarsSeed [1] filed a deletion request for python2-pyg [2]: Project dead since 2013. It wanted to be an alternative to python-pip.
Package defunct (missing dependency). I recommend to delete it. Safe to do so; nothing depends on it, and there are no user comments. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-pyg/
