MarsSeed [1] filed a deletion request for python-pygpu-git [2]: Deprecated Py2/Py3 VCS package. Upstream development discontinued since 2019. [a] The whole Theano project has ended in Dec 2022. [b] The PyMC team forked the Theano codebase and has created a new reboot project called Aesara. This libgpuarray package is not needed: python-theano is pending deletion and only optdepends on this. The PyMC project created an interim, updated fork of Theano, the AUR package for it is python-theano-pymc. The latter package does not need libgpuarray at all. So it is safe to delete this obsolete package.
