Hi all,

I just started using spynnaker (pynn with spinnaker).

I downloaded python 2.7 and pynn and spinnaker on a virtual env of mine.

I went to user/Anaconda3/envs/myenv/lib/site-package/spynnaker/spynnaker.cfg
and to /user/.spynnaker.cfg

and I added a machine name 192.168.240.253 and version = 3


I also copied the cfg file to my script directory


However, I am still stuck at a runtime error: 

File "C:\Users\20195234\Anaconda3\envs\myenv\lib\site-packages\spinn_front_end_common\interface\spinnaker_main_interface.py", line 211, in set_up_machine_specifics
    "A SpiNNaker machine must be specified your configuration"

Exception: A SpiNNaker machine must be specified your configuration file

Please advice.

Best regards,
Sherif

Hi Sherif,

You should only specify the machineName and version in one of your config files - preferably in the /user/.spynnaker.cfg file, or in the cfg file in your script directory.  Repeating it may lead to the errors you are seeing.

I would also suggest that you should be using python 3, as python 2.7 is now unsupported, and sPyNNaker works with python 3 (assuming you are using a recent version i.e. 5.0 or 5.1). 

If this still doesn't help then send us your config file in your next reply.

Andy

Hi Andrew,

Thanks for the response.

I initially tried to install it with pip install pyNN-spiNNaker

I get the following error:

Hi Sherif,

Not sure where you're getting those instructions from - that's not how we recommend installation (where did you get those instructions from?).  You need to follow the instructions at


and that should work.

Hello Andrew,


Are the tutorials out of date? The function pynn.OneToOneConnector does not accept parameters (weights delays), further more p.Projection does not accept the parameter target:


  File "C:\Users\20195234\.spyder-py3\untitled0.py", line 14, in <module>
    input_proj=p.Projection(input,pop_1,p.OneToOneConnector(weights=5.0,delays=1),target="excitatory")

TypeError: __init__() got an unexpected keyword argument 'weights'

How do you recommend starting with spynnakker? Do you have a tutorial to recommend?

Also, I attempted a run on machine 3 and it gave runtime error SpinnmanIOException: IO Error: Failed to communicate with the machine

When I attempt to run it virtually, it runs without results, giving an empty plot and numerous warning msgs: WARNING: The simulation is using a virtual machine and so has not truly ran, hence the list will be empty

Hi Sherif, anything linked from here should work with 5.1.0: http://spinnakermanchester.github.io/spynnaker/5.0.0/index.html
WORK IN PROGRESS. sPyNNaker version 5.1.0 has been released; we are currently working on the documentation. If anything here doesn’t work, please let the software team know.

I'm not sure where you've got that OneToOneConnector tutorial from, either (again, send us a link) - it's not obvious from the pypi page.  It's been that way in PyNN for a while - and a Projection should also have a synapse_type, which is why it's not accepting your target parameter (which is optional - it defaults to "excitatory").

That would suggest that your computer doesn't know the spinnaker board is connected to it.  Have you set the configuration settings correctly?  (http://spinnakermanchester.github.io/spynnaker/5.0.0/PyNNOnSpinnakerInstall.html#NetworkConfiguration).  If you've done that correctly, you ought to be able to ping 192.168.240.253 and get a response...

A few things to add to what Andy said.

1. Please use Python 3 and not the deprecated Python 2.7.  While are tools currently still work with Python 2.7 we reserve the right to withdraw this support as any time as Python 2.7 has passed its end of life.

2. You say you added machine name   "192.168.240.253".  This only works of course if you have a physical small spinnaker board attached to your PC.  If you have a physical board could you let us know the number on the white sticker on the back of it.  

3. I think the cfg file is not correct please attach a copy of this cfg in your next reply.

Christian
