Mac系统+Anaconda3+python3.8.8

安装lightgbm,xgboost这两个集成学习算法的包是成功了的
但是导入时一直报错

---------------------------------------------------------------------------
OSError                                   Traceback (most recent call last)
<ipython-input-5-b18b3f8a6dc8> in <module>
----> 1 import lightgbm

dlopen(/Users/kumahiroshi/opt/anaconda3/lib/python3.8/site-packages/lightgbm/lib_lightgbm.so, 6): Library not loaded: /usr/local/opt/libomp/lib/libomp.dylib
  Referenced from: /Users/kumahiroshi/opt/anaconda3/lib/python3.8/site-packages/lightgbm/lib_lightgbm.so
  Reason: image not found

就是一直报: OSError Reason: image not found

通过查阅资料后发现只需要在 终端 运行这行代码后重新导入即可成功:brew install libomp

brew install libomp
