Great! Sorry, yes, I overlooked the fact that you are using the "hom" synapse,
which shares (homogeneous) parameters among all instances; here, you need to use
GetDefaults() and SetDefaults() to get and set the values.
The two lines you pasted work okay for me for N = 10, gmax = 42. The error message
indicates that the "Wmax" and "weight" properties have a different
sign when running the CopyModel() line, perhaps there is an issue like N = 0?

So I changed the model from stdp_synapse_hom to
stdp_synapse and these
are my both synapses
nest.CopyModel("stdp_synapse", "stdp_synapse_exc",
{"weight":gmax,"alpha":1,"Wmax":gmax, "tau_plus":
20.0,"lambda":
-0.0005, "mu_minus": 0, "mu_plus": 0})
nest.CopyModel("stdp_synapse", "stdp_synapse_inh",
{"weight":-gmax/(N-1),"alpha":1,"Wmax":-gmax,
"tau_plus":
20.0,"lambda": 0.005, "mu_minus": 0, "mu_plus": 0})
So now I am getting properties for lambda but still it is having some issues
NESTErrors.BadProperty: BadProperty in SLI function SetStatus_CD:
Setting status of 'stdp_synapse_inh' connecting from node ID 17 to node
ID 35 via port 1: Weight and Wmax must have same sign.
I tried to change signs of lambda also while setting it but still same issue
