Hello Atiyeh,

It looks like you have multiple installations of NEST which are conflicting with each other. From the log below, the NEST that is detected is not the one installed from the source, because the version should be 3.5.0-post0.dev0 and not 3.5.

Please uninstall any old NEST installations and try again. Also, do not forget to source the nest_vars.sh file after installing it from the source.

source <nest_install_dir>/bin/nest_vars.sh

Hope this helps.

Thanks, Pooja

Dear all, I installed nest from source according to this instruction (Install NEST from source — NEST Simulator Documentation https://nest-simulator.readthedocs.io/en/stable/installation/developer.html#dev-install) but when I run this code to make a module, I face with following error. Can you help me to solve it?
