[NEST Users] Re: NESTML sample random distributions - assertion failed

Hi Chiara, Thank you for writing to us. This error is something that needs to be fixed from our side. I have created an issue for this: https://github.com/nest/nestml/issues/1016 For now, could I ask you to remove the call to random_normal() from the parameters block and instead use the PyNEST set() function for the neuron to set the random number from the simulation script? Please find some examples here: https://nest-simulator.readthedocs.io/en/stable/nest_behavior/random_number… I hope this helps! Best regards, Pooja On 18.

Specifically, I am using nest 3.6.0 nestml 7.0 This is what I would like to do: whenever creating a neuron with a set of parameters defined by the user, each parameter should be affected by a "gaussian error" with defined variability. I tried to use the internal random_normal() function but with the current version I am getting some issues there. Specifically, whenever trying to call such function from the "internals", "parameters", "state" blocks the model is correctly generated (no errors returned) but exits with en error whenever trying to "install". The error is the following Assertion failed: (tid < static_cast< size_t >( vp_specific_rngs_.size() )), function get_vp_specific_rng, file my/path/to/miniforge3/conda-bld/nest-simulator_1707218961774/work/nestkernel/random_manager.h, line 173. [1] 32875 abort python test.py Such problem does not exist for random_normal() called within the update and equations blocks. Attached some minimal code to reproduce the error.
