Python 在EC2实例上安装XGBoost

如果有人能告诉我如何在EC2上安装XGBoost，我将不胜感激。我已经设置了EC2实例并安装了Numpy/SKlearn，如下所示：

sudo yum -y install gcc-c++ python27-devel atlas-sse3-devel lapack-devel
wget https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.11.2.tar.gz
tar xzf virtualenv-1.11.2.tar.gz 
python27 virtualenv-1.11.2/virtualenv.py sk-learn
. sk-learn/bin/activate
pip install numpy

我的工作站上有一个xgb的工作实现，我通过以下方式安装：pip install xgboost。但当我在EC2上尝试此操作时，我得到了错误：

(sk-learn)[ec2-user@ip-172-31-20-221 ~]$ pip install xgboost
Downloading/unpacking xgboost

我刚刚意识到，我需要首先升级pip：

pip install --upgrade pip

不过，我将把这个问题留给其他人。谢谢
