[scikit-learn] Fwd: ValueError

[Sebastian Raschka]

Hi Ruchika,

could you maybe post the results from

$ python -c 'import numpy; print(numpy.__version__)'
1.11.0
$ python -c 'import numpy; print(scipy.__version__)'
0.17.0

just to make sure that these are indeed the latest versions? However, I suspect that this is more of a compile rather than a version issue since scikit should work fine on older versions of NumPy and SciPy — e.g., one of the CI tests is running with NUMPY_VERSION=“1.6.2” and SCIPY_VERSION="0.11.0"

Does NumPy run correctly if you run some examples without scikit-learn? 
E.g., you may want to run

import numpy
numpy.test('full')

import scipy
scipy.test('full’)

to narrow down the problem further.

And how did you compile & install scikit-learn?

Best,
Sebastian
