Hi,
Thanks, that was the problem. I was running with python2 accidentally because I forgot to
change the path to Python interpreter from the default path (#!/usr/bin/python) to the
Python 3 path I was using (#!/usr/bin/env python).
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

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!

To unsubscribe send an email to users-leave(a)nest-simulator.org 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
toy example before integrating them in my project
to make sure I am
using them as I should. So, under section "Receiving continuous
data"
in
"Guides\Using NEST with MUSIC"
(https://nest-simulator.readthedocs.io/en/stable/guides/using_nest_with_musi…),
I found a guide for this functionality of NEST,
however, the binary
"constsource" is not available. Does anybody have any idea where
I
can
find it?
Thank you very much in advance for your help,
Best wishes,
Mohammad
