在 Jupyter notebook 上导入 Xgboost 时遇到这个简单的问题

Question

在我导入 Xgboost 之前，Jupyter Notebook 中的一切都运行良好。一旦我导入它，我就会遇到以下问题。我有 Python 3.8 并且已经通过终端 pip3 方法安装了它，接下来我应该做什么？

XGBoostError                              Traceback (most recent call last)

       Mac OSX users: Run `brew install libomp` to install OpenMP runtime.
  * You are running 32-bit Python on a 64-bit OS

我通过为 Mac OSX 安装 libomp.dylib 解决了这个问题。答案一直就在那里。

您可以通过运行以下命令来完成：

brew install libomp
