I would like to make a suggestion for future development. Now there is
a Python interface, but some of us have been working with C/C++ for
many years (and we have a lot of data processing software developed in
Please, could you include a C/C++ interface for NEST?
Thanks a lot in advance!

Hello, I followed the NEST LIVE MEDIA Installation instructions, and the NEST 2.18.0 VirtualBox lubuntu 18.04_1 seems to be running fine. But then in a terminal window in the home directory, and whether running from inside ipython or python, after I type "import nest" at the prompt, I get an error message: "ImportError: dynamic module does not define init function (initpynestkernel)" (line 74 of ll_api.py). There is also another error message just before it: "Import kernel in __init__ after initializing low-level APIs" (line 28 of __init__.py)
How can this be fixed?
I am SUN, working in RIKEN, Japan.
I am working on one issue.
I am useing the GetConnections to get the weights and keep it in the text.
connections = nest.GetConnections(source, target)
When I want to update the weight with the new information.
I am using this:
But it is not working, do you have any ideas?
Dear NEST Developers!
I would like to invite you to our next bi-weekly Open NEST Developer Video Conference tomorrow
Monday 19 August, 11.30-12.30 CEST (UTC+2).
See below for information about how to log into the meeting.
The agenda for this meeting is also available online
• Review of NEST User Mailing List
• Review of open Github Pull Request
• Review of open Github Issues
See you soon!

We use a virtual conference room provided by DFN (Deutsches Forschungsnetz).
You can use the web client to connect. We however encourage everyone to use a headset for better audio quality or even a proper video conferencing system (see below) or software when available.
* Visit https://conf.dfn.de/webapp/conference/97938800
* Enter your name and allow your browser to use camera and microphone
* The conference does not need a PIN to join, just click join and you're in.
In case you see a dfnconf logo and the phrase "Auf den Meetingveranstalter warten", just be patient, the meeting host needs to join first (a voice will tell you).
How to log in with a video conferencing system, depends on you VC system or software.
- Using the H.323 protocol (eg Polycom): vc.dfn.net##97938800 or 18.104.22.168##97938800
- Using the SIP protocol:firstname.lastname@example.org
- By telephone: +49-30-200-97938800
For those who do not have a video conference system or suitable
software, Polycom provides a pretty good free app for iOS and Android,
so you can join from your tablet (Polycom RealPresence Mobile, available
from AppStore/PlayStore). Note that firewalls may interfere with
videoconferencing in various and sometimes confusing ways.
For more technical information on logging in from various VC systems,
