Can pygenn get current variables for each neuron group?

[OOOOOmoi]

In GeNN 4.X I can pull the current variables with the function pullinSyn{syn_name}FromDevice(), can I do the same thing with pygenn?

Yes you can! These variable belong to the synapse group and are accessed via SynapseGroup.out_post which gives you an Array object (https://genn-team.github.io/genn/documentation/5/source/pygenn.html#pygenn.model_preprocessor.Array) which you can interact with like any other variables (see https://genn-team.github.io/genn/documentation/5/simulating_networks.html#variables)

Are there any preconditions for using this method? Why am I prompted that out_post is a None value when I use it?

[neworderofjamie]

Ahh, it's only possible if you disable fusing of postsynaptic models:

model.fuse_postsynaptic_models = False

this will severely reduce performance but will allow you to retrieve currents

OK, I know, thanks!
