python - Theano assertion error -


when run theano , want train 2d convolutional network following error:

error (theano.gof.opt): optimization failure due to: local_abstractconv_check error (theano.gof.opt): node: abstractconv2d{border_mode='half', subsample=(1, 1), filter_flip=true, imshp=(none, none, none, none), kshp=(32, 3, 3, 3), filter_dilation=(1, 1)}(convolution2d_input_1, convolution2d_1_w) error (theano.gof.opt): traceback: error (theano.gof.opt): traceback (most recent call last):   file "c:\users\nicol\anaconda3\envs\py34\lib\site-packages\theano\gof\opt.py", line 1820, in process_node     replacements = lopt.transform(node)   file "c:\users\nicol\anaconda3\envs\py34\lib\site-packages\theano\tensor\nnet\opt.py", line 409, in local_abstractconv_check     node.op.__class__.__name__) assertionerror: abstractconv2d theano optimization failed: there no implementation available supporting requested options. did exclude both "conv_dnn" , "conv_gemm" optimizer? if on gpu, cudnn available , gpu support it? if on cpu, have blas library installed theano can link against?

i have anaconda (which includes mkl) installed python 3.4 latest version of theano. installed mingw , libpython. checked presence of blas running check_blas.py script provided theanom said theano connected blas through numpy.

i not wrong , still (obiously) want optimizers work. have seen several posts online problem none of them got real solution other installing else or not using optimizers. know how prevent error?
