Re: [TVB] Additive Noise Error in Heun Stochastic Integrator

[WOODMAN Michael]

hi

you need to check your imports.  You would usually use

from tvb.simulator import noise 

noise.Additive(nsig=np.r_[0.053])

Please check the examples in the documentation. 

cheers,

Also,  don't mind the first line of code. That should be hashed out.

Hi all,

I'm getting this error when trying to set the nsig = 0.053 

My code:

# 4. INTEGRATOR

noise = simulator.noise.Additive(nsig=0.053)

stoch_integr = integrators.HeunStochastic(dt=0.1,noise=noise.Additive(nsig=0.053))

stoch_integr.configure()

Error:

AttributeError Traceback (most recent call last) <ipython-input-33-30f51f6efe48> in <module> 1 # 4. INTEGRATOR 2 ----> 3 noise = simulator.noise.Additive(nsig=0.053) 4 5 stoch_integr = integrators.HeunStochastic(dt=0.1, noise=noise.Additive(nsig=0.053))AttributeError: module 'tvb.simulator.simulator' has no attribute 'noise' 

I've approached this in a few different ways, but I keep getting this error, or if I use noise=Additive(nsig=0.053) I get that Additive is not defined.

Cheers,

Boki

Thanks Marmaduke,

I was able to solve the problem. Regarding imports however, it seemed that I had imported everything properly. Hence why this error was a little confusing to me. 

Thanks so much for the response though - kindly appreciated!
