compilation issue when running theano
Question: 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.


Answer: 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):
