Question

我在尝试编译xgboost时遇到错误。我没有sudo访问权限，这让事情变得更加艰难。

我运行了以下内容：

git clone https://github.com/dmlc/xgboost.git --recursive
cd xgboost
make

这给了我以下错误：

您可以按照以下方式安装xgboost库以及其他基本库（请根据您的项目的库选择），我的主要关注点是使其有助于设置大多数需要sklearn的数据科学项目， pandas，scipy和xgboost算法以及可视化库。

# installing essentials
apt-get update; \
apt-get install -y \
  python python-pip \
  build-essential \
  python-dev \
  python-setuptools \
  python-matplotlib \
  libatlas-dev \
  curl \
  libatlas3gf-base && \
  apt-get clean

# upgrading pip
curl -O https://bootstrap.pypa.io/get-pip.py && \
python get-pip.py && \
rm get-pip.py
# installing libraries
pip install numpy==1.13.1
pip install scipy
pip install -U scikit-learn
pip install seaborn
pip install --pre xgboost

如果您仍然遇到环境问题，我建议您使用此Dockerfile。您可能还会发现Datmo转换有助于实现此目的。
