The second failure (`test_iterative.test_convergence`) also happens in the Barcelona build so I think this is a real issue but more investigation is required to understand what's happening."},"comment":{"url":"https://api.github.com/repos/xianyi/OpenBLAS-CI/issues/comments/206379691","html_url":"https://github.com/xianyi/OpenBLAS-CI/issues/10#issuecomment-206379691","issue_url":"https://api.github.com/repos/xianyi/OpenBLAS-CI/issues/10","id":206379691,"user":{"login":"ogrisel","id":89061,"avatar_url":"https://avatars.githubusercontent.com/u/89061?v=3","gravatar_id":"","url":"https://api.github.com/users/ogrisel","html_url":"https://github.com/ogrisel","followers_url":"https://api.github.com/users/ogrisel/followers","following_url":"https://api.github.com/users/ogrisel/following{/other_user}","gists_url":"https://api.github.com/users/ogrisel/gists{/gist_id}","starred_url":"https://api.github.com/users/ogrisel/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ogrisel/subscriptions","organizations_url":"https://api.github.com/users/ogrisel/orgs","repos_url":"https://api.github.com/users/ogrisel/repos","events_url":"https://api.github.com/users/ogrisel/events{/privacy}","received_events_url":"https://api.github.com/users/ogrisel/received_events","type":"User","site_admin":false},"created_at":"2016-04-06T13:45:33Z","updated_at":"2016-04-06T13:45:33Z","body":"Ok I did some googling (I should have started this way) and indeed the random test_nanmedia_all_axis failure should be ignored as unrelated to openblas:\r\n\r\nhttps://github.com/scipy/scipy/issues/5656\r\n\r\nSorry for the noise.
