Python AssertionError

[tux-00]

When I run "m = model.Model([300,300],[100,50], dropout=0.5)" I get a lot of this error :

<<!! BUG IN FGRAPH.REPLACE OR A LISTENER !!>> <type 'exceptions.Exception'> Constant{300} is already owned by another fgraph local_elemwise_alloc
ERROR (theano.gof.opt): Optimization failure due to: local_elemwise_alloc
ERROR (theano.gof.opt): node: Elemwise{add,no_inplace}(dot.0, Alloc.0)

    raise Exception("%s is already owned by another fgraph" % r)
Exception: Constant{300} is already owned by another fgraph

and the process is never finish (waiting about two hours). I have changed the recursion limit with sys.setrecursionlimit() to 10.000 because an exception about recursion limit appears. But nothing.

I have an I7 core, are these errors normal ?

I got the same error, and I think it is something related to the current version of theano library. I have a working version of the previous theano libarary files@ https://github.com/yunqiw/pythonlib, you can replace the folders with the ones you have, it should work
