Name conflicting in Theano

Question

I am trying to import theano in a module, but I am getting a traceback:

File "/media/tarun/6A86CA8286CA4DEF/develop/pydy/pydy/codegen/code.py", line 16, in <module>
import theano
File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 44, in <module>

from theano.gof.cc import \

File "/usr/local/lib/python2.7/dist-packages/theano/configparser.py", line 227, in AddConfigVar
configparam.fullname)
AttributeError: ('This name is already taken', 'gcc.cxxflags')

It seems that there is some name conflict in some config. Can anybody please point me to the same.

Answer 1

This error happens because some module, probably theano.gof, is imported twice. Usually, this is because a first call to import theano.gof gets started, registering 'gcc.cxxflags' in the configuration parser a first time, but then raises ImportError, which is catched and ignored. Then, import theano.gof gets called again, tries to register the option again, which raises the exception you get.

Is there any traceback or error message before this one, or something that would give a hint of why the first import failed?
