安装自定义sklearn

Question

我分叉了scikit-learn repository，添加了一个我需要的文件并下载了存储库。我不知道如何使用这个custom library。我cd'ed scikit学习主文件夹，并试图使用它，但它会引发错误。所以在阅读我使用python3 setup.py install安装它的错误之后。有两个setup.py文件。一个在scikit-learn-master文件夹和sklearn文件夹中，因此我在这两个位置都运行了python3 setup.py install。他们抛出一些警告，但没有错误。我打开蟒蛇终端在scikit-learn-master文件夹，并使用import sklearn返回如下 -

Traceback (most recent call last): 
    File "/Users/shubhamgandhi/Desktop/scikit-learn-master/sklearn/__check_build/__init__.py", line 44, in <module> 
    from ._check_build import check_build # noqa 
ModuleNotFoundError: No module named 'sklearn.__check_build._check_build' 

During handling of the above exception, another exception occurred:

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. 

我不知道如何着手。有什么我失踪？

看起来该模块没有被正确构建。所以它显示check_build的importError。

在使用pip安装模块之前，请确保已安装所有依赖项。在自述文件中，提到包：

Python (>= 2.7 or >= 3.3) 
NumPy (>= 1.8.2) 
SciPy (>= 0.13.3) 
For running the examples Matplotlib >= 1.1.1 is required. 

如果您不打算参与该项目，但只使用它，建议您从https://pypi.python.org/pypi/scikit-learn下载分叉它代替。

查看有关如何安装here的详细说明。

安装完成后，如果仍有问题，可以参考http://scikit-learn.org/stable/faq.html获取常见问题解答。
