Cannot compile simple PyCuda OSX application
Question: I've followed the PyCuda instructions here:
<http://wiki.tiker.net/PyCuda/Installation/Mac>

I'm trying to compile the following code:

    
    
    import pycuda.autoinit
    import pycuda.driver as drv
    import numpy
    
    from pycuda.compiler import SourceModule
    mod = SourceModule("""
    __global__ void multiply_them(float *dest, float *a, float *b)
    {
      const int i = threadIdx.x;
      dest[i] = a[i] * b[i];
    }
    """)
    
    multiply_them = mod.get_function("multiply_them")
    
    a = numpy.random.randn(400).astype(numpy.float32)
    b = numpy.random.randn(400).astype(numpy.float32)
    
    dest = numpy.zeros_like(a)
    multiply_them(
            drv.Out(dest), drv.In(a), drv.In(b),
            block=(400,1,1), grid=(1,1))
    
    print dest-a*b
    

And I'm receiving the following error:

    
    
    > python test.py
    
    Traceback (most recent call last):
      File "test.py", line 12, in <module>

    [stderr:

    ]
    

I've searched google and found the following threads, but they don't help
solve the issue;

TIA!


Answer: So the problem is that I hadn't installed a minor update from the nvidia
control panel. After that and updating my bash_profile it works. Heh.
