How to delete point(already inserted) in subdiv2d (python)

I implemented subdiv2d and insert some points as the following way to construct Delaunay triangulation.

size = img.shape
rect = (0, 0, size[0], size[1])
subdiv  = cv2.Subdiv2D(rect)
points = []
x = 0
while(x<size[0]):
    y = 0
    while(y<size[1]):
        points.append((x, y))
        y = (y + 50)
    points.append((x, size[1]-1))
    x = x + 50

subdiv.insert(points)

I want to remove some points after that, let's assume I want to remove (0, 0), or (50,50) point from subdiv, that I already inserted through point array. How can I do this? please help me.
