Error while sending a spike using PyNN - SpiNNaker

Asked 2020-Jul-22 at 12:31

I am trying to send a single spike to neuron 18 of the population I created using connection.send_spike(label, 18). The code I am using is the same as the example on Jypiter which runs correctly there.

You are assigning the result of session.run() to a. This means a is a numpy array after the first run, overwriting the original definition as a placeholder. Then you are using this array as a key in the dictionary for the second run, which obviously doesn't work.

Renaming the a and b variables within the session context should fix it, e.g.
