Theano 0.7 nose failed 270 out of 19842 tests

I follow the instruction here: http://ift.tt/1ULLkCF with

Visual Studio 2010 cuda 5.5 GTX 760 WinPython

Configured Theano for GPU use

But when I ran Theano's test suite: theano-nose --batch I got these: E:\Theano\Theano>theano-nose --batch -s Using gpu device 0: GeForce GTX 760

############################## RUNNING TESTS IN BATCHES OF 100

3% done in 17.261s (failed: 4) 6% done in 19.026s (failed: 8) 10% done in 8.650s (failed: 9) 13% done in 152.198s (failed: 9) 16% done in 349.837s (failed: 9)

It's only 16% of all the tests, but it already failed some tests, do I need to reinstall theano?
