[Numpy-discussion] test failures when numpy built without atlas libraries.

[Charles R Harris]

When built without ATLAS, the following tests fail :

======================================================================
ERROR: check_testUfuncRegression (numpy.core.tests.test_ma.test_ufuncs)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/numpy/core/tests/test_ma.py", line
691, in check_testUfuncRegression
    self.failUnless(eq(ur.filled(0), mr.filled(0), f))
  File "/usr/lib/python2.5/site-packages/numpy/ma/core.py", line 1552, in
filled
    result = self._data.copy()
  File "/usr/lib/python2.5/site-packages/numpy/ma/core.py", line 1474, in
_get_data
    return self.view(self._baseclass)
TypeError: Cannot change data-type for object array.

FAIL: Ticket #588
----------------------------------------------------------------------
Traceback (most recent call last):
  File
"/usr/lib/python2.5/site-packages/numpy/core/tests/test_regression.py", line
734, in check_dot_negative_stride
    assert_equal(np.dot(x,z),np.dot(x,y2))
  File "/usr/lib/python2.5/site-packages/numpy/testing/utils.py", line 143,

    return assert_array_equal(actual, desired, err_msg)
  File "/usr/lib/python2.5/site-packages/numpy/testing/utils.py", line 225,

  File "/usr/lib/python2.5/site-packages/numpy/testing/utils.py", line 217,

    assert cond, msg
AssertionError:
Arrays are not equal

(mismatch 100.0%)
 x: array([[ 55924.]])
 y: array([[ 640000.]])


When built with ATLAS the second test passes, but the
check_testUfuncRegression error persists. This is at revision 4807.
