You're likely passing an int for the r_gpu parameter. The problem is that PyCuda is refusing to guess what type the Python 'int' may correspond to. You have to tell it. There are two ways: - Use numpy's sized integers in the direct invocation interface. (convenient) - Use the prepared_call interface. [1] (recommended) In this case, you don't have to pass sized ints any more, since you've already specified arg types in prepare(). I've updated the docs to make this clearer.
