If I run the same notebook in my Linux installation I only need to set it to 0.0001.\r\n\r\nOn another test, if I run Google's Deep Dream notebook in my mac Caffe I randomly get `Inf`s during the forward pass. I.e. my forward pass will always go to infinity at some point, but it's not always during the same iteration. The same doesn't happen in my Linux installation. \r\n\r\nMy mac installation was compiled in El Captain with Anaconda, Boost 1.61 and Apple's BLAS. All tests run OK during compile time.\r\n\r\nDoes anybody know what is causing this and how to fix it? \r\n\r\nThank you!"},"comment":{"url":"https://api.github.com/repos/BVLC/caffe/issues/comments/268403893","html_url":"https://github.com/BVLC/caffe/issues/5107#issuecomment-268403893","issue_url":"https://api.github.com/repos/BVLC/caffe/issues/5107","id":268403893,"user":{"login":"mary-alegro","id":18488529,"avatar_url":"https://avatars.githubusercontent.com/u/18488529?v=3","gravatar_id":"","url":"https://api.github.com/users/mary-alegro","html_url":"https://github.com/mary-alegro","followers_url":"https://api.github.com/users/mary-alegro/followers","following_url":"https://api.github.com/users/mary-alegro/following{/other_user}","gists_url":"https://api.github.com/users/mary-alegro/gists{/gist_id}","starred_url":"https://api.github.com/users/mary-alegro/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mary-alegro/subscriptions","organizations_url":"https://api.github.com/users/mary-alegro/orgs","repos_url":"https://api.github.com/users/mary-alegro/repos","events_url":"https://api.github.com/users/mary-alegro/events{/privacy}","received_events_url":"https://api.github.com/users/mary-alegro/received_events","type":"User","site_admin":false},"created_at":"2016-12-21T00:56:21Z","updated_at":"2016-12-21T00:56:21Z","body":"So, I have a version of Atlas compiled from scratch in my system. However I can't make caffe to link against it, no matter what I do. It always finds vecLib. I've tried both the standard way editing Makefile.conf and using cmake. Would you have any suggestion on how to get rid of vecLib?"}}
