Has enyone faced this problem? Please can you help me?

Hi @SMajic, and welcome to the Nengo forums. :grinning:

Without the actual model, it’s a little difficult to tell exactly what is causing this issue. However, I would hazard a guess that this error is being caused by a function in a Nengo.node. Functions that are provided to Nengo.node are evaluated at x=0 when the model is built (i.e., when you make the nengo.Simulator object), so you will need to be careful that the Node’s function does not contain a singularity at that point.
