Comment(by warren.weckesser):

 The test passes if eps is changed from 1e-7 to 1e-6.  Several other
 float32 tests on the iris data set use eps=1e-6:
 {{{
 test_pdist_euclidean_iris_float32      eps = 1e-06
 test_pdist_seuclidean_iris_float32     eps = 1e-05
 test_pdist_cosine_iris_float32         eps = 1e-07
 test_pdist_cityblock_iris_float32      eps = 1e-06
 test_pdist_correlation_iris_float32    eps = 1e-07
 test_pdist_minkowski_3_2_iris_float32  eps = 1e-07 (fail; passes with
 1e-6)
 test_pdist_minkowski_5_8_iris_float32  eps = 1e-06
 test_pdist_chebychev_iris_float32      eps = 1e-06
 }}}
 Any objections to simply changing the tolerance to 1e-6?
