Undeclared Identifier Error for Multiple Runs #129
Description
Hey there! I was running my first code on Brian2Genn, and I was trying to run the code multiple times on the same Jupyter Notebook File. It seems as though the code is looking for objects in the previous run, as it sometimes gives no error and plots a graph and other times gives the undeclared identifier error. I was wondering if I was using the device.activate() and device.reinit() methods properly, or if there is something else that I am missing.
from brian2 import *
import brian2genn
%matplotlib inline
set_device('genn')
device.reinit()
device.activate()
start_scope()
G = NeuronGroup(1, 'v : 1', threshold='v>0.6', reset='v=0', method='exact')
G.v = '0.6'
SM = StateMonitor(G, 'v', record=True)
print("Completed without Errors")
run(100*ms)
print("Ran without Errors")
plot(SM.t/ms, SM.v[0])
device.reinit()
device.activate()
