reset_device() and run() results in 'Only a single run statement is supported'

[JustasB]

In Multiple Runs section in documentation it states that:

code can be run repeatedly “in multiple runs” that are completely independent. This just needs a reset_device command issued after the run(runtime) command

However, I get a the 'Only a single run statement is supported' error when I try to run() after device_reset()

Smallest code to reproduce the error:

from brian2 import *                   
import brian2genn   
set_device('genn')
run(1*second)

from brian2.devices import reset_device
reset_device('genn')

run(1*second) # <- results in above error

Hi,
thanks, that's indeed incorrect/outdated in the documentation. The correct way is to use device.reinit() and device.activate() as described for the C++ standalone mode in Brian2 : https://brian2.readthedocs.io/en/stable/user/computation.html#multiple-builds

I.e., the following should work for Brian2GeNN as well:

from brian2 import *
import brian2genn
set_device('genn')
run(1*second)

device.reinit()
device.activate()

run(1*second)

@mstimberg Thank you, it's working. Also, thank you for updating the docs.
