在 Debian 上使用 conda 安装 xgboost
Install xgboost using conda on Debian
当我尝试使用以下命令安装 conda 时 conda install -c aterrel xgboost=0.4.0
,出现错误
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
给我
NoPackagesFoundError: Package missing in current linux-64 channels:
- xgboost
何修复它并安装 xgboost?
从 conda 4.3.5 开始,没有选项可以将通道指定为 conda info
。所以要打印包裹的信息,你可以这样做:
(root) ~/condaexpts $ conda config --add channels aterrel
(root) ~/condaexpts $ conda info xgboost

您也可以在manifest频道查看相同的信息。
回到您最初的查询,出现了冲突,因为 aterrel's channel 中的包 xgboost

而不是针对 python 3.5
构建包名称中的构建字符串 py27
也很明显。
但是,您可以为 python 3.5
