Hi

I am currently encountering below issues when trying to install any version of Scikit Learn (0.19.0 or 0.19.1 or 0.19.2)

Python Version - 3.7

/usr/local/bsb-python37 - Custom Location in which I configured and installed Python 3.7

I have installed all the prerequisite - OS packages - bias-devel , lapack-devel , atlas-devel. 

Earlier when I installed Python 2.7 I didn't run into any issues. Now when I re-try to install the scikit learn under Python 2.7 I am running into the same issue and the earlier successful installed version of scikit learn is corrupted.

Error
# /usr/local/bsb-python37/bin/python3.7 setup.py install --prefix=/usr/local/bsb-python37
Partial import of sklearn during the build process.

Any help is greatly appreciated. I tried to google around and did all that I could try. No luck.

Thanks,

Have you reported this upstream to the scikit-learn folks? scikit-learn is not part of core Python, so there's probably not a lot we can do here.

Hi Mark,

Thank you for your update. How do I reach to the upstream scikit-learn folks ?

Thanks,
Abhishek
