HI,
So, I tried to run the script on a NEST live media downloaded from NEST
website (
https://nest-simulator.org/downloads/gplreleases/lubuntu-18.04_nest-2.16.0.…).
I did this because I imagined that Python2/3 mix up shouldn't be a problem
in the live media. However, I got a similar error.
Best,
Mohammad

Hi!
Your error looks a lot like a Python 2/3 mixup to me. This usually
happens if you compile NEST against Python 2, while you run it using
Python 3, or the other way around. Please make sure that your
environment is consistent with respect to Python versions.
Please note that we're not supporting Python 2 in all future versions of
NEST, as it (finally!) reached it's well-deserved end of life.
Cheers,
Jochen!

Dear Jochen,
Thank you very much! Found it there. However, I got the following error,
this time, from the python script (given as an example on the website,
attached anyways). Maybe this is important for you to know that, with my
current compilation of NEST and MUSIC, I could successfully run MUSIC
for two NEST simulations communicating spike events between the two.
OS: Ubuntu 18.04.4 LTS, NEST v2.16.0 compiled by cmake downloaded from
https://github.com/INM-6/closed-loop-learning-in-autonomous-agents

Dear Mohammad,
the constsource binary is not part of NEST, but of MUSIC. After
building
and installing MUSIC, you will find it in
<MUSIC_INSTALL_PREFIX>/lib/music-<MUSIC_VERSION>.
Cheers,
Jochen!

Dear all,
I am trying to use music ports for my simulations, which requires
continuous transmission of data to NEST. I would like to test
them in a

them as I should. So, under section "Receiving continuous
data" in
"Guides\Using NEST with MUSIC"

Thank you very much in advance for your help,
Best wishes,
