[SOLVED] Error starting the simulation

#1

Good evening,

I am running simulations on the NRP (and SpiNNaker) and everything was working until I tried to delete some objects and the simulation unexpectedly timed out. After that I tried launching the same simulation and I was getting this error:

(UnrecognizedContentError(<hbp_nrp_commons.generated.exp_conf_api_gen.ExD_ object at 0x7f4f380fd2d0>, <pyxb.binding.content.AutomatonConfiguration object at 0x7f4f380fdb50>, <pyxb.utils.saxdom.Element object at 0x7f4f3819ca90>, pyxb.utils.utility.Location(None, 23, 2))) (host: spinn-20.cs.man.ac.uk)

Does anyone have an idea what it means? I am thinking that there is a problem related to the fact that I was editing the environment while the simulation timed out and now the configuration is invalid?

Dear Gabija,

Environment modifications are not automatically saved, you’d have to save them manually with a button click. So, I don’t think your edition ruined the environment file. Though, it might be that other experiment file got corrupted for some reason. Can you push your .exc, .bibi and .exd files here? You can find them by selecting your experiment and clicking the “Files” button.

Best regards
Axel

Here is a link to the files: https://drive.google.com/drive/folders/1BNv-D2ukM3TeQiQYAZhqlPaY7no_ILGa?usp=sharing

However, I have never created/saw/used files with exd extension, nor have I seen them in example experiments, therefore, I zipped .bibi and .exc files. Please tell me if there something else I should attach.

This might help as well (extended error message):

I managed to pin down that it is a problem with user-settings.uis file. However, I have not found the solution yet.

#6

Dear Gabija,

So your user-settings file is not in the provided zip, but you can safely empty it manually and if it does not help remove its reference from the .exc file (remove the complete tag … but leave the ending </ns1:ExD> tag!

Try this out.
Best regards,
Axel

Thank you for your time and answers, I have created a new experiment and moved the essential files to it and it works. I will look into the problem with the broken experiment sometime, if it happens again with my new simulation. Once again, thank you for your answers.

Best regards
