ImportError: Numerical Python (NumPy) is not installed.

[andrecp]

Hello, I a trying to use the buildpack in my heroku project.

My requirements.txt has

numpy==1.8.1
scipy==0.14.0
scikit-learn==0.17b1

I am using python-2.7.10

I've done

heroku buildpacks:set https://github.com/thenovices/heroku-buildpack-scipy

I get

ImportError: Numerical Python (NumPy) is not installed.

I got some error in the process like

Any idea what I could do? Thanks

I've tried python 2.7.8 and numpy==1.7.0 scipy==0.11.0 scikit-learn==0.13.1

but no joy...

If I go with

numpy==1.9.2
scipy==0.15.1

I get

           Running from numpy source directory.

but then

Running into this today w/- Python 3.5.2 numpy==1.9.2 scipy==0.15.1

[branliu0]

This buildpack doesn't support python 3

I'm all ears to this one...
