Error using SpiNN Local board #1093

Closed lungsi closed 3 years ago

lungsi commented 5 years ago

Python: 2.7 sPyNNaker8

pip show sPyNNaker8
Name: sPyNNaker8
Version: 1!4.0.0
Summary: Tools for simulating neural models generated using PyNN 0.8 on the SpiNNaker platform

Board: SpiNN-3 DMC, ST, Sep11

As per instructions I set my wired network settings as

But I noticed that the machineName = 192.168.240.253 in the instructions as well as in the nengo_spinnaker.conf.example so I set IP address = 192.168.240.254.

I then pinged

root@6ff47bec99ee:/# ping -w3 192.168.240.253

Now in my local .spinnaker.cfg I set

machineName = 192.168.240.253
version = 3

and ran the example synfire_if_curr_exp.py but I got IO Error: Failed to communicate with the machine

andrewgait commented 5 years ago

I think your second error is occurring because you have something like "version = 3 # None" rather than "version = 3" in the config file. You can't have comments on the same line as a value like that in a config file, as far as I'm aware.

I'm not quite sure what's going on with your first error, though - the machineName and version values are correct for a standard spinn-3 board. Are the LEDs on the board flashing / on at all? If they are, as a first attempt, try resetting it by pushing the white button and then running your script again...

andrewgait commented 5 years ago

Hang on, I've just re-read what you said above and now I'm not sure what you've set your network settings IP address to. It should be 192.168.240.254 (the address of the adapter) not 192.168.240.253 (the address of the board).

lungsi commented 5 years ago

Thank you @andrewgait I corrected the network setting where IP Address = 192.168.240.254 while the machineName = 192.168.240.253, i.e, they now have different addresses.

The board is still not recognized

I tried again by pushing the "white" reset button for few seconds and the led came back on and four other led started flickering (as it did earlier). But I still got the same error.

lungsi commented 5 years ago

Since I have set the wired IP address to the board's adapter 192.168.240.254, I can ping that 192.168.240.254 but I can't ping 192.168.240.253 anymore.

Is there a command to see if my computer can shake hands with the board, for instance via 192.168.240.253?

rowleya commented 5 years ago

If you can't ping the address, the tools won't be able to speak to the board; ping is the test that has to work, or else the board won't work. I would go back and make sure your setting are as you think they are, and that the cable is properly connected to your computer and to the SpiNNaker board. Also make sure that you are using the correct subnet mask when setting up your network.

PS: Also I have made sure there are no loose connections by connecting, disconnecting, powering off/on and pushing the reset button. Besides, if I disconnect I can't ping 192.168.240.254 so its unlikely due to cable connectivity.

andrewgait commented 5 years ago

It's possible then that you have a board whose machine address has been set to a different value. Does your board have a black number on a white background on it (usually in the centre of the four chips)?

lungsi commented 5 years ago

I don't know but it has the number 35 as black font on white background.

lungsi commented 5 years ago

Also, below shows that pinging from 0 to 255 (253 being the default spinn-3 machine) results in only one hit.

andrewgait commented 5 years ago

Thanks for the further information. We currently have this board (35) listed as being with Andrew Davison in Paris - is that who you got it off, and are you working with him? Our next suggestion would be to try to find out from him whether he either changed the board address or knows what it is.

lungsi commented 5 years ago

Yes I am working with Andrew. I will get in touch with him and ask if he remembers changing the board address.

PS: Does that mean I can also change the board address to its default machineName = 192.168.240.253?

andrewgait commented 5 years ago

No - the machineName (the board address) is what will have been changed. You said above that the only address that you could ping was 192.168.240.254 - this is the adaptor to the board and should be what you set in your network settings.

Please let us know what you find out from Andrew Davison and we’ll take it from there.

After looking into the configuration in Andrew's laptop where it was last known to work. I used it and now it works.

Hi,

I'm in a similair siutation. I am using a Spinn-5 board (031) which I got from another group.

I am wondering if my problem is also caused by the alteration of the default IP address on my spinn-5 board? I asked the people I got the board from and he has no idea how the board has been used before. Is there any chance I can reset the IP address?

best, le

andrewgait commented 3 years ago

It sounds like the default address is different. @lplana has a list of boards somewhere, so he might be able to help here... ?

lplana commented 3 years ago

This is one of the 3 boards that Alan had in Edinburgh.

In case that it helps, I found an old email from Alan asking about the process to change the IP addresses of one of his boards. I'm not sure if it refers to this board though. He wanted the following changes:

192.168.240.0 which has mac address -00-00-a4-f0-00-00 to move to ip address 129.215.63.136 192.168.240.1 which has mac address -00-00-a4-f0-00-01 to move to ip address 129.215.63.137

andrewgait commented 3 years ago

Oh, it's the other one of Alan's old boards (I have the other two), in which case I think the IP address you need to use might be 192.268.2.203 (based on the conversation I had with him when setting up the other two boards here).

Please let us know which IP address works and we'll update our records.

Helloworld-Le commented 3 years ago

Thank you for your quick reply! I have tried all of them and none is working. I also tried changing the network configuration. Can you check again the IP (192.268.2.203), should it be 192.168.2.203 or something else? In each case, after changing the machine name to the new IP address in .spynnaker.cfg, how should I modify the network configuration?

andrewgait commented 3 years ago

Apologies, yes, the machineName in the config file should be 192.168.2.203. The network configuration should still be 192.168.240.254, but if that still doesn’t work then try 192.168.2.254 instead.

Helloworld-Le commented 3 years ago

I tried

Network Address: 192.168.240.254 machineName: 192.168.2.203

Network Address: 192.168.2.254 machineName: 192.168.2.203

Network Address: 192.168.240.254 machineName: 192.168.240.203

Sadly, none of them is working.

My desktop is connected to WiFi and then using a cable connects the Spinn-5 board (I also tried switching between the 2 Ethernet ports on the spinn-5 board, also used different cables).

andrewgait commented 3 years ago

I'm afraid I'm not sure what else we can try here. Can I check again what you have set in your network configuration settings? It should (I think) be:

IP address: 192.168.2.254 Subnet mask: 255.255.255.0 (It looked like you may have set 255.255.0.0 from your output above?)

and then in the cfg file:

machineName = 192.168.2.203

If this still doesn't work another option I guess is a video call where you share your screen and we try to troubleshoot it. If you need to do this then let me know (email andrew.gait@manchester.ac.uk) and we can probably arrange something.

rowleya commented 3 years ago

From the above, shouldn't the IP address of the board be 129.215.63.137?

In that case, you would need to set your IP address to something in that range e.g. 129.215.63.254, with a subnet mask of 255.255.255.0.

Note that this is an official IP address probably from Edinburgh. If you are using this with a cable connected only between your computer and the board, this should be fine, but note that it could otherwise interfere with communications, particularly if you ever connect to the Edinburgh network that this was connected to. I am mainly saying this to trigger a memory of this message in case that ever happens!

Helloworld-Le commented 3 years ago

Hi @andrewgait , I certainly tried what you said but it was not working last time. But it is working now!

I haven't realized what else I changed but I can confirm this board is now working with:

MachineName = 192.168.2.203 IP address: 192.168.2.254 Subnet mask: 255.255.255.0

Also, there is only one Ethernet port working with the above configuration. Is this something that should happen? (I am already happy with having one port working correctly.)

andrewgait commented 3 years ago

Hi, glad to hear you have it working! Only one of the ports should be working if I remember correctly (I think the lower one of the two), the other is for the BMP.
