Question

I need to input 3, 3D points as a matrix into this function; so I made a tuple like this one:

initPoints = ([10,20,30],[5,15,25],[100,150,200])

but I got the following error:

AttributeError: 'tuple' object has no attribute 'shape'

The same thing happened when i used a list. any ideas? what is ‘shape’? do i need some other kind of array? How can I do that?
Thanks

Edit – the function I’m using is scipy.cluster.vq.kmeans2 with minit=’matrix’

Answer 1

As the docs to scipy.cluster.vq.kmeans2 indicate, k should be a numpy.ndarray when you pass in minit='matrix'. So do this:

initPoints = numpy.array([[10,20,30],[5,15,25],[100,150,200]])
