Dear Gustavo, Could you give us more context? Are you running the script in Jupyternotebook or simply running the python script. For the former case, I suggest first to restart the notebook Kernel. For the latter case, could you elaborate more on how you build the nestml module and where do you install it in your file system. Best, Ayssar ________________________________ From: gustavo.patow(a)udg.edu <gustavo.patow(a)udg.edu> Sent: Thursday, April 20, 2023 8:59:28 PM To: users(a)nest-simulator.org Subject: [NEST Users] Reloading and debugging a nestml module Hi, Continuing with my exploration, I am now developing my own nestML module. I successfully compiled it and ran it without errors or problems. However, the result was not what I expect, so I modified the nestML code, compiled it, and... well, I tried to re-install it with nest.Install("nestmlmodule") and I get an error that the module was already loaded. When I try to rerun my simulation, I get the old result, not the new one. How do I do to reload the module? I've searched through the documentation and I do not find any reload, reinstall, or anything similar... Is there any other way than killing everything and starting over from scratch? By the way, are there any debug tools for a nestML module? I tend to make zillions of mistakes, and any way of inspecting the behavior of the module and the state of the internal variables would be of incredible help! thanks!!! gus.- _______________________________________________ NEST Users mailing list -- users(a)nest-simulator.org To unsubscribe send an email to users-leave(a)nest-simulator.org ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.

Hi! Reloading modules in NEST is currently not possible. We are working on this, but it might still be some weeks until the feature will become available. The only solution for now is to restart Python or your Jupyter Kernel. Regarding debugging of NESTML models, in addition to what Maryada said, the most obvious answer is to just print out things, see here: https://nestml.readthedocs.io/en/v5.2.0/nestml_language/nestml_language_con… Cheers, Jochen!
