I want to make some changes to sklearn code and use the library without installing it.
I have downloaded the source from github and made the required changes.
But when I try to import a module, it gives me an error
No module named _check_build
It seems that scikit-learn has not been built correctly.
What should I do to use modified sklearn without installing it?
Check this link https://github.com/scikit-learn/scikit-learn#development
And what you really need is to install sklearn from source code. You must install sklearn before use it. Installation does not only means pip install sklearn, but also means you need to build it from source before use.
