Machine learning 无法从jupyter笔记本安装lightgbm

在jupyter笔记本中，我做到了：

!pip3 install lightgbm

我得到了以下信息：

Requirement already satisfied: lightgbm in /Users/tiger/anaconda/lib/python3.5/site-packages (2.2.1)
Requirement already satisfied: scikit-learn in /Users/tiger/anaconda/lib/python3.5/site-packages (from lightgbm) (0.18.1)

它显示该软件包已安装。但是，当我尝试导入lightgbm时：

import lightgbm as lgbm

我得到了以下信息：

安装

libomp

为我修复了这个问题（MacOS）：

在Linux中，这应该是：

sudo apt install libomp-dev

---

在macOS上对我很有效

$ brew install lightgbm
