Hello guys,
After struggling for a while, I just finished the installation of scipy using the intel mkl library.
Ungracefully the tests ended with an error regarding "undefined symbol: ATL_buildinfo" (see below)
Can this scipy installation live with this error? or Is it prone to throw out wrong computations?
The only failure is a check of the ATLAS version, that shouldn't yield incorrect results.
Also, why the number of ran test is not a fix number
Not sure. Perhaps nose isn't counting the one ATLAS test when it passes, due to that file not having any actual tests in it.
(running the tests using a scipy/Atlas installation finished succesfully indicating: Ran 5832 tests in 422.155s OK (KNOWNFAIL=14, SKIP=42), but the scipy/mkl tests ended with Ran 5833 tests in 448.386s FAILED (KNOWNFAIL=14, SKIP=34, errors=1))?
what is the meaning of KNOWNFAIL=14?
Knownfail indicates tests that are known to fail under some conditions (usually hardware/compiler dependent), so they aren't reported as new errors/failures. If we wouldn't do this, we would keep getting the same bug reports over and over again. Ralf
