Hi
Running Ubuntu 16.10, installed anaconda3, theano from conda-forge. Nothing
works due to the errors below.
I've tried various options for the cxx flag, g++-5 g++-4.9 /usr/bin/g++-4.8
etc
The theanorc file is recognized as it correctly picks up the gpu when that
is enabled, but still fails to compile.
Any help please :)
