[nengo-user] Problem with WhiteNoise - - 2D decision integrator (Nengo 2 Tutorials Chapter 8)

[Néstor Rueda(Universidad Nacional)]

Hi,

When, I run the attachment file (2D_decision_integrator.py based on the
example - chapter8 sent by Chris Eliasmith link
<https://github.com/s72sue/Nengo2-Tutorials/tree/notebook_tutorials/chapter8>),
I have the next error:

line 21, in <module>
    MT = nengo.Ensemble(100, dimensions=2,
noise=WhiteNoise(dist=Uniform(-0.3,0.3)))
TypeError: __init__() got an unexpected keyword argument 'dist'

This error stems from lines 21 to 23:

    MT = nengo.Ensemble(100, dimensions=2,
noise=WhiteNoise(dist=Uniform(-0.3,0.3)))
    LIP = nengo.Ensemble(200, dimensions=2,
noise=WhiteNoise(dist=Uniform(-0.3,0.3)))
    output = nengo.Ensemble(100, dimensions=2,
noise=WhiteNoise(dist=Uniform(-0.3,0.3)))

But if i replace the noise parameter with

noise=nengo.processes.WhiteNoise(duration=6.0)

the program work's but the output doesnt't have noise.

Can anyone tell me how to solve this problem? Many thanks in advance.
