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，总是显示以下错误。

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。

Answer 1

对我来说，即使一切都在64位上，我仍然会遇到此错误。

最后，我发现 XGBoost需要在Windows计算机中安装Visual Studio 2017 C ++ Redistributable。。
