Description
Hi Evgeni,
I have followed the instructions you have provided, downloaded the library, and run the setup.py. However, I do get this error
Error compiling Cython file:

Could you please let me know how to fix this issue? Also, is there any update about incorporating this split method into Sklearn?
Many thanks in advance for your response.
