python - Optimization failure in theano -


i using fedora anaconda python environment. have 960m nvidia gpu, have installed required drivers , cuda toolkit. when try run theano tests, end getting following error (in huge error output):

ee.eeeerror (theano.gof.opt): optimization failure due to: constant_folding error (theano.gof.opt): node: dimshuffle{x}(tensorconstant{2}) error (theano.gof.opt): traceback: error (theano.gof.opt): traceback (most recent call last):

i trying compile simple function y, when first saw error. searching solution led me find lot of people had same problem test function, without definite solutions. followed theano documentations , set $cuda_root cuda root folder, no avail.

i'm using theano version 0.8.2 , numpy 1.11.1, both conda repos. seems gpu issue. if has problems, shouldn't fallback cpu?

any highly appreciated. thanks!
