安裝xgboost使用Debian的

暢達當我嘗試用下面的命令conda install -c aterrel xgboost=0.4.0安裝暢達，我有一個錯誤安裝xgboost使用Debian的

UnsatisfiableError: The following specifications were found to be in conflict: 
    - python 3.5* 
    - xgboost 0.4.0* 
Use "conda info <package>" to see the dependencies for each package.

命令conda info xbgoost給我

NoPackagesFoundError: Package missing in current linux-64 channels: 
    - xgboost

何來修復它，並安裝xgboost ？

截至conda 4.3.5，沒有選項指定通道到conda info。所以打印封裝的信息，你可以這樣做：

(root) ~/condaexpts $ conda config --add channels aterrel                                    
(root) ~/condaexpts $ conda info xgboost

(root) ~/condaexpts $ conda config --remove channels aterrel

您還可以查看從該通道的manifest相同的信息。

回到你原來的查詢，有出現，因爲aterrel's channel包xgboost只被建爲python 2.7而不是爲python 3.5由此也可見一斑通過包名構建字符串py27衝突。

你可以，但是，它建爲python 3.5：

(root) ~/condaexpts $ wget https://anaconda.org/aterrel/xgboost/0.4.0.c4fa2f/download/linux-64/xgboost-0.4.0.c4fa2f-py27_0.tar.bz2 
(root) ~/condaexpts $ tar -xf xgboost-0.4.0.c4fa2f-py27_0.tar.bz2 -C /tmp/xgboost/ 
(root) ~/condaexpts $ conda install conda-build -y 
(root) ~/condaexpts $ conda-build /tmp/xgboost/info/recipe 
(root) ~/condaexpts $ conda install xgboost --use-local -y
