Requesting sklearn package for EECS127/227a

[matteociccozzi]

Adding the requirement for sklearn for EECS127/227a.

[matteociccozzi]

From scikit-learn website:

scikit-learn requires:
Python (>= 3.6)
NumPy (>= 1.13.3)
SciPy (>= 0.19.1)
joblib (>= 0.11)
threadpoolctl (>= 2.0.0)

looks like we may need to add:

• SciPy == 0.19.*
• joblib == 0.*
• threadpoolctl == 2.0.*

Let me know if this seems correct and I can add these lines.

@yuvipanda I can't seem to pass the eecs image build, I'm not sure why.

I believe maybe the dependencies need to be updated? jupyterhub/repo2docker#724

Thanks for catching that, @matteociccozzi! I've upgraded repo2docker, let's see how this goes.

Looks like that worked, thank you!
