Hiya, When using clustering in scikits_learn, after upgrading to 0.15.1 I got the following error when doing a simple import: >>> import sklearn.cluster Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.7/site-packages/sklearn/cluster/__init__.py", line 6, in <module> from .spectral import spectral_clustering, SpectralClustering File "/usr/lib64/python2.7/site-packages/sklearn/cluster/spectral.py", line 13, in <module> from ..utils import check_random_state, as_float_array File "/usr/lib64/python2.7/site-packages/sklearn/utils/__init__.py", line 11, in <module> from .validation import (as_float_array, check_arrays, safe_asarray, File "/usr/lib64/python2.7/site-packages/sklearn/utils/validation.py", line 17, in <module> from .fixes import safe_copy File "/usr/lib64/python2.7/site-packages/sklearn/utils/fixes.py", line 18, in <module> from .testing import ignore_warnings File "/usr/lib64/python2.7/site-packages/sklearn/utils/testing.py", line 36, in <module> from nose.tools import assert_equal ImportError: No module named nose.tools emerging dev-python/nose solves the problem.
Just fixed it, thanks for the report.
