Hi everyone,
While using an OpFromGraph involving some operations with binary values,
there is an optimization error:
theano.gof.opt: ERROR: Optimization failure due to: local_add_canonizer

This error does not happen when running on CPU backend.
I suspect it might be due to the use of binary values in my code, but the
log message is not very helpful, is there any way to get some more
information to track down the error? Note that the fast_compile optimizer
does not trigger the error, only the fast_run one.
A demo code and the complete output is available here:

Best,
Nicolas
