VisPy example: interactive cloud of points in 3D

points.py

import sys
import numpy as np
from vispy import app, scene

canvas = scene.SceneCanvas(keys='interactive')
view = canvas.central_widget.add_view()
view.set_camera('turntable', mode='perspective', up='z', distance=2,
                azimuth=30., elevation=30.)

pos = .25 * np.random.randn(1000, 3)
colors = np.random.uniform(size=(1000, 3), low=.5, high=.8)

p1 = scene.visuals.Markers()
p1.set_data(pos, face_color=colors)

view.add(p1)

if __name__ == '__main__':
    canvas.show()
    if sys.flags.interactive == 0:
        app.run()

Hi! It's giving me an error saying

File "points.py", line 15, in
p1.set_data(pos, face_color=colors)
"ValueError: color must be of correct shape"

is this an error with vispy? it seems that the color vector has the right size (1000,3)...

Any ideas? thanks!
