我无法在python3上导入scikit -learn.如何导入它

Question

我成功安装了numpy-1.13.1+mkl-cp36-cp36m-win32 .whl和scipy-0.19.1-cp36-cp36m-win32.whl，然后我成功安装了scikit-learn，但是当我运行导入sklearn时，Pycharm给了我错误。如何消除此问题？我在Windows 3.6（32位）上安装了python10（64位）。

import sklearn

运行结果：

C:UsersEmertatAppDataLocalProgramsPythonPython36-32python.exe "F:/Python/NS videos/cedes/Exercise 07 test.py"

首先，使用以下命令从您的 Windows 操作系统中删除 sklearn-

pip uninstall scikit-learn

然后，您需要从他们自己的官方安装程序中安装 numpy 和 scipy。

用于

pypi scikit-learn 的轮子包（.whl 文件）可以使用 pip 实用程序安装。打开控制台并键入以下内容以安装或升级到最新的稳定版本：

pip install -U scikit-learn

如果没有与您的python匹配的二进制软件包，您可以尝试从Christoph Gohlke非官方Windows安装程序或python发行版安装scikit-learn及其依赖项。
