sklearn ImportError：没有名为_check_build的模块

Question

我正在尝试导入 sklearn，但是当我尝试这样做时，我收到以下信息：

 ---------------------------------------------------------------------------

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line string', (1, 2))

我相当确定 scikit-learn 已正确构建，因为我成功运行了 python setup.py install 没有任何事故。但是我确实尝试运行 python setup.py bdist_wininst -b doc/logos/scikit-learn-logo.bmp 尽管在 error: cannot copy tree 'build\scripts.win-amd64-2.7': not a directory 被打断了。

可能有人知道如何解决这个问题吗？

我在 Windows 10 上遇到了同样的问题。我用 Python 3.7 安装了 Anaconda，这个安装不仅解决了这个问题。要解决在 anaconda 提示符下运行：

 conda install scikit-learn

至少这对我有用
