问题描述
我在为venv 3.8.5安装xgboost时遇到问题。命令pip install xgboost或pip3 install xgboost不起作用。当我尝试使用anaconda安装xgboost时，我得到了
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- py-xgboost -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.5,<3.6.0a0']
Your python: python=3.8
If python is on the left-most side of the chain,that's the version you've asked for.
When python appears to the right,that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The following specifications were found to be incompatible with your system:
- feature:/win-64::__cuda==9.1=0
- feature:|@/win-64::__cuda==9.1=0
Your installed version is: 9.1
因此，我决定使用滚轮安装xgboost。他们建议在页面Click Here上下载我想要的提交ID并使用
pip install <url to the wheel>
可以在Click Here处找到滚轮的网址。我下载了适用于Windows的最新轮子，然后打开了cmd，并出现以下错误

我只是想知道合适的轮子是什么，与降级当前的Python版本相比，我还有哪些其他选择
