python - Compilation error when importing Theano on Windows 7 -


i'm trying use theano on windows 7. able install theano , import theano, after seeing warning not having c compiler installed installed mingw. when try "import theano" compilation error. message rather long, relevant parts (from tell) this:

problem occurred during compilation command line below: g++ -shared -g -d npy_array_ensurecopy=npy_ensurecopy -d npy_array_aligned=npy_aligned -d npy_array_writeable=npy_writeable -d npy_array_update_all=npy_update_a ll -d npy_array_c_contiguous=npy_c_contiguous -d npy_array_f_contiguous=npy_f_contiguous -m64 -dms_win64 -ic:\python27\lib\site-packages\numpy\core\include -ic: \python27\include -o c:\users\ameasure\appdata\local\theano\compiledir_windows-7-6.1.7601-sp1-intel64_family_6_model_58_stepping_9_genuineintel-2.7.3-64\lazylin ker_ext\lazylinker_ext.pyd c:\users\ameasure\appdata\local\theano\compiledir_windows-7-6.1.7601-sp1-intel64_family_6_model_58_stepping_9_genuineintel-2.7.3-64\l azylinker_ext\mod.cpp -lc:\python27\libs -lc:\python27 -lpython27 g++: error: createprocess: no such file or directory

and later in error message this:

any idea i'm doing wrong? files referenced in compile statement don't exist, may part of problem, doesn't explain why theano thinks should there.

installation on windows isn't trivial. simplest way use epd(not free version, miss depenency). academic? if so, free. install theano dependency, need install theano after , link mkl blas.

we had theano installer worked anaconda 1.4, newer released anaconda 1.5 broke it. haven't repaired yet.
