Error in NESTML when I run the 'NESTML Izhikevich tutorial' - NEST Users

28 Feb 2022


      Hi,
after following the guide in "https://nestml.readthedocs.io/en/latest/installation.html" related to the NESTML installation, I tried to follow the NESTML Izhikevich tutorial in "https://nestml.readthedocs.io/en/latest/tutorials/izhikevich/nestml_izhikevi...". After installing the cmake with "pip install cmake", when I execute the following part of the tutorial:
generate_nest_target(input_path="izhikevich_solution.nestml",
                     target_path="/tmp/nestml-component",
                     logging_level="ERROR",
                     codegen_opts={"nest_path": NEST_SIMULATOR_INSTALL_LOCATION})
I obtain the following error:
line 3:2 extraneous input 'state' expecting {<EOF>, NEWLINE, 'neuron', 'synapse'}

I can't solve it. Can anyone help me?
