I installed theano on windows 8, 64 bit. I am using anaconda implementation, python 3.4. Trying to install theano, I diligently followed all steps on this link (which helped on another computer with similar configuration):
http://rosinality.ncity.net/doku.php?id=python:installing_theano (English and Korean)
whenever I type 'import theano' on my IDE (pycharm) I get a long error message, but I believe the most meaningful portion is:
import theano
>>>>Exception: Compilation failed (return status=1):
C:\Users\xxx\AppData\Local\Theano\compiledir_Windows-8-6.2.9200-
Intel64_Family_6_Model_69_Stepping_1_GenuineIntel-3.4.3-
64\lazylinker_ext\mod.cpp:1: sorry, unimplemented: 64-bit mode not compiled in
Would sincerely appreciate some input btw, I installed mignw64, msys, and all other dependencies.
I found the problem. the path environment variable was not pointing to the correct mingw-w64 (which is needed to run theano on 64 bit windows) directory.
The environment variable should always point to the bin subdirectory of the mingw-w64 directory, as in:
C:\Users\xxxxx\Anaconda3\mingw-w64\mingw64\bin
Again, the following post is VERY USEFUL to install theano on 64-bit windows (in English and Korean):
