如何编辑scikit-learn的分叉副本？

Question

我正在尝试编辑sklearn提供的NMF软件包。

为此，我分叉并克隆了自己的sklearn副本。

但是，我正在努力导入我的sklearn的克隆和编辑副本，而不是标准版本。因为，如果我只是尝试写

import sklearn

我导入标准版本，而不是我自己的编辑版本。另一方面，如果我尝试将目录中的名称更改为please_work，则会出现以下错误：

ImportError: No module named 'please_work.sklearn.__check_build._check_build'
___________________________________________________________________________
Contents of /home/jovyan/please_work/sklearn/__check_build:
setup.py                  __pycache__               _check_build.pyx
__init__.py
___________________________________________________________________________
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.

我完全不知所措，非常感谢您的帮助！
