[scikit-learn] Fwd: ValueError

[Ruchika Nayyar]

Hello Sebastian

Thanks for some insight.. So here are some of my responses

1) $ python -c 'import numpy; print(numpy.__version__)'

1.8.0rc1

2)  python -c 'import numpy; print(scipy.__version__)'

Traceback (most recent call last):

  File "<string>", line 1, in <module>

NameError: name 'scipy' is not defined



And I installed everything using pip install numpy/scikit-learn
and so on.
But when I tried to do this

pip install --upgrade scipy

Requirement already up-to-date: scipy in /Library/Python/2.7/site-packages

Requirement already up-to-date: numpy>=1.6.2 in
/Library/Python/2.7/site-packages (from scipy)



So not sure why it is not being defined.
Thanks,
Ruchika
