Hello SKLearn community,
Following up on a thread a few days ago on errors encountered running
nosetests sklearn. Providing the details below as requested.
Installation is based on git clone of:
- https://github.com/fonnesbeck/ScipySuperpack
- https://github.com/scikit-learn/scikit-learn
Running Mac OSX 10.7.4. It's not important to me to have cutting-edge
versions of the code. Just looking for a stable version to learn and get
started.
Also, relevant output from pip freeze:
-
- ipython==0.13.beta1
- matplotlib==1.2.x
- nose==1.1.2
- ## FIXME: could not find svn URL in dependency_links for this package:
- numpy==1.8.0.dev-e15d0bd-20120629
- scikit-learn==0.12-git
- scipy==0.10.1
- sklearn==0.0.0
& nosetest results below.
Thank you.
-Michael
