Unfortunately, when I try to run the the code in a TF
nrp.config.brain_root.pp.get_connections()
while having the following function defined in a pp
's class in the brain file:
def get_connections(self):
return nest.GetConnections(self.columns_pre, self.columns)
where the class attributes are simply
self.columns_pre = nest.Create("iaf_cond_exp", 1200, params=cell_params)
self.columns = nest.Create("iaf_cond_exp", 1200, params=cell_params)
the simulation in online NRP 3.2.0 slows down so much, that it seems that it freezes (even the real time and timout counters stop). One step of the CLE takes almost two minutes. There are around 16 000 connections between the two populations but I have already used the nest.GetConnections()
function on these populations within the brain file (without TFs) and the initialisation of the simulation did not take so long. Is such a slowing down when using TFs inevitable?
