Hi Chris,
Sorry for the confusion. For NEST synapses, you need to specify a variable in the model
that will be treated as a special "synaptic weight" variable (could be a state
or a parameter), and another variable that will be treated as "synaptic delay"
(can only be a parameter). There is some documentation about this feature on
https://nestml.readthedocs.io/en/latest/running/running_nest.html#dendritic…,
but the error messages are a bit cryptic. I have filed a pull request to make the errors a
bit more user-friendly at https://github.com/nest/nestml/pull/1098. Thanks very much for
the feedback and please let us know if you run into any further issues.
With kind regards,
Charl

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#generatin…
And see here for a usage example:
https://nestml.readthedocs.io/en/latest/tutorials/stdp_windows/stdp_windows…
Hope this helps!
With kind regards,
Charl

I’m working with the nestml 7.0.2. I got the
example models from
https://github.com/nest/nestml/blob/v7.0.2/models/neurons/hill_tononi.nestml this git
tree. I tried three different stdp models including stdp_triplet_naive.nestml. All give
AssertionError: Synapses only support one spiking input port
when I generate_target in python.
