MarsSeed [1] filed a deletion request for pysolo [2]: Proposal to delete this niche scientific Python2 package, discontinued since 2015. [a] Its AUR dependency, wxpython has build problems, so this also cannot be used. But there are no votes or comments. PyPI/pysolo is an actively maintained, completely unrelated library.
