I'm new to theano, so please be patient :) I have a function where I get y as a parameter. Now I want to debug-print the shape of this y to the console. Using print y.shape results in the console output (i was expecting numbers, i.e. (2,4,4) ): Shape.0 Or how can I print the numerical result of for example the following code (this counts how many values in y are bigger than half the maximum): errorCount = T.sum(T.gt(T.abs_(y),T.max(y)/2.0)) errorCount should be a single number

For me it looks like Numpy was compiled with a different Fortran version than Theano. I already reinstalled Theano ( sudo pip uninstall theano + sudo pip install --upgrade --no-deps theano ) and Numpy / Scipy ( apt-get install --reinstall python-numpy python-scipy ), but this did not help. What steps would you recommend? Complete error message: ImportError: ('/home/Nick/.theano/compiledir_Linux-2.6.35-31-generic-x86_64-with-Ubuntu-10.10
