Package: src:bottleneck Severity: important Dear Maintainer,
In my attempt to investigate why xarray fails to test with the packaged bottleneck [1], I have looked at its packaging and enabled the test suite by adding the missing b-deps on python[,3]-nose. [1] https://github.com/pydata/xarray/issues/1208 However, the tests fail for both Python 2 and 3 with the following log: ``` ====================================================================== FAIL: test move functions ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 729, in chk_same_position assert_array_equal(x_id, y_id) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 871, in assert_array_equal verbose=verbose, header='Arrays are not equal') File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 796, in assert_array_compare raise AssertionError(msg) AssertionError: Arrays are not equal (mismatch 8.333333333333329%) x: array([[ True, True, False, False, False, False], [False, False, False, False, False, True]], dtype=bool) y: array([[ True, True, False, False, False, False], [False, False, False, False, False, False]], dtype=bool) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nose/case.py", line 198, in runTest self.test(*self.arg) File "/home/gvaillan/workspace/debian/packages/bottleneck/build/lib.linux-x86_64-3.5/bottleneck/tests/move_test.py", line 42, in unit_maker aaae(actual, desired, decimal, err_msg) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 979, in assert_array_almost_equal precision=decimal) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 761, in assert_array_compare chk_same_position(x == +inf, y == +inf, hasval='+inf') File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 735, in chk_same_position raise AssertionError(msg) AssertionError: Arrays are not almost equal to 5 decimals func move_median | window 4 | min_count 1 | input a50 (float32) | shape (2, 6) | axis -1 | order C Input array: [[ inf 7. -inf -9. -10. nan] [ nan 5. 4. nan nan inf]] x and y +inf location mismatch: x: array([[ inf, inf, 7. , -1. , -9.5, -10. ], [ nan, 5. , 4.5, 4.5, 4.5, inf]], dtype=float32) y: array([[ inf, inf, 7. , -1. , -9.5, -10. ], [ nan, 5. , 4.5, 4.5, 4.5, 2. ]], dtype=float32) ====================================================================== FAIL: test reduce functions ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 729, in chk_same_position assert_array_equal(x_id, y_id) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 871, in assert_array_equal verbose=verbose, header='Arrays are not equal') File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 796, in assert_array_compare raise AssertionError(msg) AssertionError: Arrays are not equal (mismatch 33.33333333333333%) x: array([False, False, True], dtype=bool) y: array([False, False, False], dtype=bool) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nose/case.py", line 198, in runTest self.test(*self.arg) File "/home/gvaillan/workspace/debian/packages/bottleneck/build/lib.linux-x86_64-3.5/bottleneck/tests/reduce_test.py", line 63, in unit_maker assert_array_almost_equal(actual, desired, decimal, err_msg) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 979, in assert_array_almost_equal precision=decimal) File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 761, in assert_array_compare chk_same_position(x == +inf, y == +inf, hasval='+inf') File "/usr/lib/python3/dist-packages/numpy/testing/utils.py", line 735, in chk_same_position raise AssertionError(msg) AssertionError: Arrays are not almost equal to 5 decimals func nanmedian | input a61 (float32) | shape (3, 4) | axis -1 | order C Input array: [[ inf 7. -inf -9.] [-10. nan nan 5.] [ 4. nan nan inf]] x and y +inf location mismatch: x: array([-1. , -2.5, inf], dtype=float32) y: array([-1. , -2.5, 2. ], dtype=float32) ---------------------------------------------------------------------- ``` It also fails if you run the build and test manually with: ``` python[,3] setup.py build cd build/lib* python[,3] -m nose ``` Please consider investigating this with upstream.
