python-scikit-learn uses features of python-six that were only introduced in the six-1.6 release. Notably, the allowance of multiple base classes in six.with_metaclass To duplicate the exception, try running this example script. http://scikit-learn.org/stable/auto_examples/plot_digits_classification.html#example-plot-digits-classification-py Installing six-1.6.1 directly from upstream fixes the issue.
Could you explain what error or exception are you getting? I can run the exampl without apparent problems python-scikit-learn-0.14.1-5.fc20.x86_64 python-six-1.5.2-1.fc20.noarch
Weird. I can't duplicate the issue anymore. Thanks for responding! I'll close as not-a-bug.
