The reason for this is the installation of pyhull. Is there any chance that pyhull could just be replaced by the scipy implementation?\r\n\r\nAs a side note, even the maintainer of pyhull states that the scipy implementation is actually 50% faster:\r\n(from the pyhull Readme.md - https://github.com/materialsvirtuallab/pyhull)\r\n\r\n\"At the time of development of pyhull, the scipy.spatial package was the only other package that supports the computation of higher dimensional convex hulls. However, the version of scipy at that time (scipy 0.11.0) only supported the computation of Delaunay triangulation and the convex hull was computed from the Delaunay triangulation, which is slower and less reliable than directly computing the convex hull. As of version 0.12.0, scipy now supports the direct computation of convex hulls and is in fact ~50% faster than pyhull for larger hulls. I will still make pyhull available for the simple reason that the scipy package is fairly large and not everyone wants to install such a large package for computing hulls.\"\r\n\r\nAs scipy is anyway a requirement for pymatgen, it would make sense to reduce the dependencies.\r\n\r\nClemens"},"comment":{"url":"https://api.github.com/repos/materialsproject/pymatgen/issues/comments/162304808","html_url":"https://github.com/materialsproject/pymatgen/issues/281#issuecomment-162304808","issue_url":"https://api.github.com/repos/materialsproject/pymatgen/issues/281","id":162304808,"user":{"login":"shyuep","id":577107,"avatar_url":"https://avatars.githubusercontent.com/u/577107?v=3","gravatar_id":"","url":"https://api.github.com/users/shyuep","html_url":"https://github.com/shyuep","followers_url":"https://api.github.com/users/shyuep/followers","following_url":"https://api.github.com/users/shyuep/following{/other_user}","gists_url":"https://api.github.com/users/shyuep/gists{/gist_id}","starred_url":"https://api.github.com/users/shyuep/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/shyuep/subscriptions","organizations_url":"https://api.github.com/users/shyuep/orgs","repos_url":"https://api.github.com/users/shyuep/repos","events_url":"https://api.github.com/users/shyuep/events{/privacy}","received_events_url":"https://api.github.com/users/shyuep/received_events","type":"User","site_admin":false},"created_at":"2015-12-06T11:28:25Z","updated_at":"2015-12-06T11:28:25Z","body":"Try the latest beta: https://github.com/materialsproject/pymatgen/releases/tag/v3.2.8b and let me know if it works."}}
