Hello,

I am doing a RNN project with Theano and so far it has been working great.

Now I have a class written in Python (which reads a pre-trained net and 
runs it frame-by-frame for real time execution) which I want to plug into a 
different C++ project. This class has been tested in Python to be working 
as intended.

I'm using pybind11, a C++11 wrapper for Python's C API, for embedding a 
Python interpreter in C++ and interacting with it. This binding seems to 
work well. On a test Python class (different from the one mentioned above), 
I can toss std::vector<float> objects to it and retrieve back from it a 
random NumPy.ndarray object with matching values on both Python/C++ sides. 

But when I run the real thing, where a theano.function object maps the 
input to the output, everything else seems to work fine until the function 
object is called, then the function object returns a nan. This does not 
happen when I use this class through plain python (e.g., via 
THEANO_FLAGS=device=gpu0,etc python test.py). I have no clues what is 
happening.

A few questions:
- Is this a known issue? Is Theano not supposed to be used in Python 
embedded in other languages?
- Are there some things I can try to fix this issue?

I'm using Theano 0.9dev4 with the latest version of libgpuarray.

Thanks for any input!
