The sPyNNaker code based has moved on to use PyNN 0.9 and Neo 0.6
Therefor we no longer support the creation of new models based on sPyNNaker7.
The repositories for this can be found at sPyNNaker8
The new model templates for sPyNNaker8 can be found at sPyNNaker8NewModelTemplate
For help converting existing models (ideally to sPyNNaker8/ PyNN 0.9) please contact the Spinnaker team
