I recommend using `Anaconda` or `Miniconda` python release for easier dependency resolution on `numpy` `scipy` and `scikit-learn`, and update `pip` (`setuptools`) to the most recent version.\r\n\r\nBefore typing `pip install xgboost` and happy waiting, please follow the instruction on the PyPI page as copied here:\r\n\r\n* Since this package contains C++ source code, pip needs a C++ compiler from the system to compile the source code on-the-fly. Please follow the following instruction for each supported platform.\r\n* Note for Mac OS X users: please install `gcc` from `brew` by `brew tap homebrew/versions; brew install gcc --without-multilib` firstly.\r\n* Note for Linux users: please install `gcc` by `sudo apt-get install build-essential` firstly or using the corresponding package manager of the system.\r\n* Note for windows users: this `pip` installation may not work on some windows environment, and it may cause unexpected errors. pip installation on windows is currently disabled for further investigation, please install from Github.\r\n\r\nIf everything is fine, after hearing CPU fan noise for couple of minutes (it is compiling on the fly), one should see something like this:\r\n<img width=\"1001\" alt=\"screen shot 2016-08-09 at 2 59 16 am\" src=\"https://cloud.githubusercontent.com/assets/1690881/17513065/afadf0aa-5ddf-11e6-985a-e98d2dbf484a.png\">\r\n\r\nThis package is tested with Mac OS X 10.10, ubuntu 14/16 and CentOS 7 with no problem. Please report any issues or installation difficulties here, with detailed information. For having the debug output, please use `pip install -v xgboost`. Thanks.\r\n"},"comment":{"url":"https://api.github.com/repos/dmlc/xgboost/issues/comments/239054276","html_url":"https://github.com/dmlc/xgboost/issues/1446#issuecomment-239054276","issue_url":"https://api.github.com/repos/dmlc/xgboost/issues/1446","id":239054276,"user":{"login":"garyci","id":8717007,"avatar_url":"https://avatars.githubusercontent.com/u/8717007?v=3","gravatar_id":"","url":"https://api.github.com/users/garyci","html_url":"https://github.com/garyci","followers_url":"https://api.github.com/users/garyci/followers","following_url":"https://api.github.com/users/garyci/following{/other_user}","gists_url":"https://api.github.com/users/garyci/gists{/gist_id}","starred_url":"https://api.github.com/users/garyci/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/garyci/subscriptions","organizations_url":"https://api.github.com/users/garyci/orgs","repos_url":"https://api.github.com/users/garyci/repos","events_url":"https://api.github.com/users/garyci/events{/privacy}","received_events_url":"https://api.github.com/users/garyci/received_events","type":"User","site_admin":false},"created_at":"2016-08-11T01:46:38Z","updated_at":"2016-08-11T01:46:38Z","body":"@byronliwei           brew install clang-omp"}}
