在Jupyter Notebook上导入Xgboost时遇到此简单问题

Question

在我导入Xgboost之前，在Jupyter笔记本电脑上一切正常。导入后，立即出现以下问题。我有Python 3.8，并已通过终端pip3方法安装了它，下一步该怎么办？

Likely causes:

       libomp.dylib for Mac OSX, libgomp.so for Linux and other UNIX-like OSes). 
       Mac OSX users: Run `brew install libomp` to install OpenMP runtime.
  * You are running 32-bit Python on a 64-bit OS

Answer 1

我通过安装Mac OSX的libomp.dylib解决了该问题。答案一直在那里。

Answer 2

对于Mac OSX，只需运行“ brew install libomp”

Answer 3

您必须先在您的 MAC 上安装 brew：https://brew.sh/（Brew 可能需要一些时间来安装） 然后在终端中运行以下命令：brew install libomp

Answer 4

如果你使用anaconda，你可以使用：

conda install py-xgboost

Answer 5

如果你有 Python 3.7 或更高版本，你可以按照下面的方法解决：

!brew install libomp

Answer 6

如果您使用的是 anaconda，下面的命令对我有用

conda install -c conda-forge xgboost
