Furthermore, I had to change a lot of indizes to int(index).

The function def dist_point_to_segment is depreceated from mpl. I had to add it manually.

def dist_point_to_segment(p, s0, s1):
    """
    Get the distance of a point to a segment.

      *p*, *s0*, *s1* are *xy* sequences

    """
    p = np.asarray(p, float)
    s0 = np.asarray(s0, float)
    s1 = np.asarray(s1, float)
    v = s1 - s0
    w = p - s0

    c1 = np.dot(w, v)
    if c1 <= 0:
        return dist(p, s0)

    c2 = np.dot(v, v)
    if c2 <= c1:
        return dist(p, s1)

    b = c1 / c2
    pb = s0 + b * v
    return dist(p, pb)
