3 years ago Hi @ErbB4. Thanks for reaching out to us. I believe you have installed NESTML through pip. If so, the version of NESTML installed (4.0) is not compatible with NEST 2.20.2. Is there a specific requirement for you to use this NEST version? If not, could I ask you to use the latest NEST version (3.1) and try to compile it again?
conda install -c conda-forge nest-simulator=3.1If you do want to use NEST 2.20.2, we support that in NESTML now as mentioned here but unfortunately, it is not yet released as a pip package. For this to work, you would have to install NESTML from Github as mentioned here. Please feel free to reach out to us if you face any issues.

Hi there,
I am trying to install NESTML to implement my own model. I managed to install it but had difficulty running your tutorial code. In detail, I am testing using the tutorials and ran into some bugs when the code was trying to
makethe c++ code.Bug
Following the instructions in the documentation, the Izhikevich tutorial produces errors when
make.A few things:
echo $LD_LIBRARY_PATH: /tmp/nestml-component-> x86_64-conda-linux-gnu-c++Error logs
