Error when running tests

Hi, I am getting following error:

Traceback (most recent call last):

    return self._points[self._points.shape[0] / 2]
IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices

Do you know what can be the problem?

[cjekel]

In Python 3

    return self._points[self._points.shape[0] / 2]

creates an error because the division of two integers is a float.

You'll need to change the line to something like

    return self._points[self._points.shape[0] // 2]

which will need to be done in a few places in this library.

I did this, but now I have different errors, ellipse estimator. Does this library work on your machine?

[cjekel]

@VCasecnikovs I don't remember. I can't seem to find a local copy on my machine, and I don't have a fork on github...

Maybe check the network graph, there were a couple up commits from others https://github.com/horiken4/ellipse-detection/network that could fix issues.
