I'm trying to use the GPUArray class to allocate and fill a vector array.
>>> from pycuda import autoinit
>>> autoinit.device.name()
'GeForce GTX 470'
>>> from pycuda import gpuarray
>>> a_gpu = gpuarray.GPUArray(100, dtype=gpuarray.vec.float3)
>>> a_gpu.fill(gpuarray.vec.make_float3(0.0, 0.0, 0.0))
Traceback (most recent call last):

AttributeError: 'numpy.dtype' object has no attribute 'declarator'
Do GPUArray's support the vector types?
