It was straight forward to install nestml 8.0.0.  The version is 8.0.0-rc2.  I got the integrate_and_fire_neuron model from the latest models , and that worked.  I then tried a noisy_synapse, and that didn’t work.  Nor did static_synapse or stdp_synapse. 

 

I get a

 

KeyError: ‘static_synapse’

From nest_code_generator.py

delay_variable = self.get_option(“delay_variable”)[synapse_named_stripped]

 

with the error pointing to synapse_name_stripped.  This is the same error I get with the other two synapses.

 

Any thoughts?

Hi Chris,

 

We have a release candidate out for NESTML 8.0.0, as there were some big changes since the last version, could I ask you to work with that? It should be easy to install using "pip install --pre nestml"; please let us know if you run into any issues.

 

To generate the code for an STDP synapse, you need to tell the code generator that there is one spiking input in the synapse model that should be connected to the postsynaptic partner. Please see here for documentation:

 

https://nestml.readthedocs.io/en/latest/running/running_nest.html#generating-code-for-plastic-synapses

 

And see here for a usage example:

 

https://nestml.readthedocs.io/en/latest/tutorials/stdp_windows/stdp_windows.html

 

Hope this helps!

 

With kind regards,

Charl
