SpikeSourcePoisson produces an error while getting data after a reset if another population is recorded.

[Anna Bulanova]

Poisson source get_data produces an error after p.reset(), if there is a second population being recorded.

import spynnaker8 as p

import numpy as np



#pre_rate = 100

n_nrn = 1



p.setup(1)



simtime = 100



pop_src2 = p.Population(n_nrn, p.SpikeSourcePoisson(rate=100), label="drive")

pop_ex = p.Population(n_nrn, p.IF_curr_exp(), label="test")

proj2 = p.Projection(pop_src2,  pop_ex,  p.OneToOneConnector(),

               synapse_type=p.StaticSynapse(weight=2.0),  receptor_type='excitatory')



pop_src2.record('spikes')

pop_ex.record('spikes')

p.run(simtime)

trains = pop_ex.get_data('spikes').segments[0].spiketrains

trains2 = pop_src2.get_data('spikes')

p.reset()

p.run(simtime)

print 2

trains = pop_ex.get_data('spikes').segments[0].spiketrains

trains2 = pop_src2.get_data('spikes')

p.end();



print "\n job done"
