Question

我已使用pip for Python 2.7.16成功安装了xgboost（我在macOS High Sierra上使用Homebrew安装了此Python版本）。我的问题是，按照以下错误消息，我无法在Python中导入xgboost：

mac-128644:~ user$ python

xgboost.core.XGBoostError: XGBoost Library (libxgboost.dylib) 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): ['dlopen(/usr/local/lib/python2.7/site-packages/xgboost/./lib/libxgboost.dylib, 6): Library not loaded: /usr/local/opt/gcc/lib/gcc/8/libgomp.1.dylib\n  Referenced from: /usr/local/lib/python2.7/site-packages/xgboost/./lib/libxgboost.dylib\n  Reason: no suitable image found.  Did find:\n\t/usr/local/lib/python2.7/site-packages/xgboost/./lib/libxgboost.dylib/libgomp.1.dylib: stat() failed with errno=20']

我已经确保我的Python版本和OS都是64位的，因此问题绝对不是第二个“可能的原因”。我也很确定我已经安装了OpenMP：查找说明，就我而言，我会brew install llvm进行安装，并且安装成功。我也不确定为什么似乎找不到/usr/local/lib/python2.7/site-packages/xgboost/./lib/libxgboost.dylib，因为我可以cd进入该目录并看到libxgboost.dylib很好。看起来稍后在它 did 找到它的消息中，但仍然抛出错误？到底发生了什么，我该怎么办才能解决此错误？
