XGBoost安裝錯誤

Question

我嘗試編譯xgboost時遇到錯誤。我沒有sudo訪問，這讓事情變得更加棘手。

我跑了以下內容：

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

使我有以下錯誤：

您可以與其他必要的庫一起如下安裝xgboost庫（請選擇基於足夠的庫對於你的項目），我的主要焦點在於爲大多數需要sklearn，pandas，scipy和xgboost算法以及可視化庫的數據科學項目提供幫助。

# 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 

如果您仍然遇到環境問題，我建議使用此Dockerfile。您可能還會發現Datmo轉換對此很有幫助。
