当我尝试将 scikit learn 导入我的 python 3.5（jupyter notebook）时，我得到了这个错误：

from sklearn.model_selection import train_test_split

scikit learn 0.18.2 软件包已经安装，当我运行conda list 时，我可以在列表中看到它（我在上一个版本 0.19.1 上遇到了同样的错误）。

我使用 Anaconda 3 (conda 4.2.2)

【解决方案1】：

您的 python 安装缺少 scipy 使用的动态链接共享库。

通常当您在 lib 目录下安装 anaconda 时，此共享对象会存在，并且相应的路径会在环境中导出以进行动态链接。

检查此文件是否在您安装的 anaconda 的 lib 目录下。

例如：- /anaconda3/lib/libquadmath.0.dylib

如果它不存在，请重新安装 anaconda 它将解决您的问题。如果此文件存在，请检查您的环境路径。列表中必须有 anaconda 安装路径。
