Theano is failing it's tests when I do:
python -c "import theano; theano.test();"
If these are known failures, shouldn't it still pass? IE when I test other libraries, KnownFailures sometimes trigger, but the overall test still passes with "OK" (but will still note the KnownFails and Skipped tests).
My guess is this is ok, and the test really is "passing", but since I'm doing a fresh install following the deeplearning.net tutorials, and I'm getting this error, I assume others might have this question as well, and a search on Google, and SO, isn't really helpful.
Forgive the error-code-dump, I am sure no one will need to read all through this, but it's here for reference if someone else has this question. Here are the errors at the end of the tests:
