In [3]: s = cuda.Stream() In [4]: s.handle Out[4]: 32994256 Works a treat; although you do need to ensure that a reference to the object is retained. Saying that, it is no more risky than having to manually manage a stream using the C API. I've been using the above in my ctypes cuBLAS wrappers for a while now. Regards, Freddie.
