MarsSeed [1] filed a deletion request for python2-msgpack-numpy-git [2]: Nothing depends on this Python2 VCS package from 2015, so I recommend deletion.
Upstream supports Python3; there is a stable and a VCS package on AUR for that. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-msgpack-numpy-git/
