test_csr_row_norms
did not have a fixed random_state so failure is hard to catch. It appeared in #16499, see https://dev.azure.com/scikit-learn/scikit-learn/_build/results?buildId=13730&view=logs&jobId=91634bb0-5686-577d-d1fa-65c16f031456The issue is that the default rtol (1e-7) of
assert_allclose
is not adapted to float32 because in that case machine precision is ~1.2e-7.
