Hi,

the Interact command does not seem to be working in Sage 7.3 Jupyer 
Notebook!


Here is the code from a notebook cell:
-----------------------------------------------------------------
from ipywidgets import interact, interactive, fixed
import ipywidgets as widgets


def plotNthRoots(n):
    # Create a unit circle
    c = circle((0,0), radius=1, rgbcolor=(1,0,0))
    # Combine the circle with points on the circle representing the roots 
of unity
    theta = 2.0*pi/float(n)
    p = c + point([(cos(t), sin(t)) for t in srange(0, 2.0*pi, 
theta)],frame=True,size=60)
    # Add in vectors from the origin to the roots of unity.
    p = p + sum([arrow2d( (0,0), (cos(t),sin(t)) ) for t in srange(0, 
2.0*pi, theta)])
    show(p)
    print("The Principle %d-Root: (%5.3f)+(%5.3f)I"%(n,cos(theta), 
sin(theta)) )

    
@interact
def _(n=(1,20)):
    plotNthRoots(n)
---------------------------------------------------------

Rather than creating a slider, it generates a plot for the case n=20.

Any suggestions?
