xgboost错误:不是有效的Win32应用程序

Question

我想使用XGBoost。当我尝试执行代码时，它总是显示下面给出的错误。

Exception has occurred: xgboost.core.XGBoostError
XGBoost Library (xgboost.dll) could not be loaded. Likely causes:   * OpenMP 
runtime is not installed (vcomp140.dll or libgomp-1.dll for Windows, 
libgomp.so for UNIX-like OSes)   * You are running 32-bit Python on a 64-bit 
OS Error message(s): ['[WinError 193] %1 is not a valid Win32 application']

我安装了xgboost，下载了dll文件并安装了它。

对我来说，即使一切都是64位的，我仍然有这个错误。

最后，我发现XGBoost需要安装在windows机器.中的VisualStudio2017 C++可再发行版。
