Calling __host__ functions in PyCUDA

Is it possible to call __host__ functions in pyCUDA like you can __global__ functions? I noticed in the documentation that pycuda.driver.Function creates a handle to a __global__ function. __device__ functions can be called from a __global__ function, but __host__ code cannot. I’m aware that using a __host__ function pretty much defeats the purpose of pyCUDA, but there are some already made functions that I’d like to import and call as a proof of concept.

As a note, whenever I try to import the __host__ function, I get:

pycuda._driver.LogicError: cuModuleGetFunction failed: named symbol not found
