在 Anaconda 上安装 xgboost 时遇到问题

Question

我尝试过对 xgboost 进行 pip 安装，但由于我公司计算机上的防火墙设置而未成功。

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000002000411CD48>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/xgboost/

我尝试从以下站点下载 xgboost 0.90 软件包：https://anaconda.org/anaconda/py-xgboost/files 并对其进行了 conda 安装。安装过程中没有产生任何错误。当我尝试导入它时，出现错误。

Traceback (most recent call last):

C:\ProgramData\Anaconda3\lib\site-packages\xgboost\./windows/x64/Release/xgboost.dll

对于如何解决回溯错误的任何帮助，我们将不胜感激。或其他不涉及 pip 安装的 xgboost 安装替代方案。谢谢

我最终从以下网站下载了 xgboost whl 文件：https://www.lfd.uci.edu/~gohlke/pythonlibs/#xgboost 和运行它的 pip 安装。似乎正在工作。
