Question

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实例和安装numpy的/ SKlearn这样的：

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 

我有XGB我的工作站，这是我通过安装在工作实现：PIP安装xgboost。但是，当我尝试这在EC2上，我得到的错误：
