When installing Nest, I encountered the following error " Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/yao/Documents/nest-simulator-2.16.0-build/lib/python2.7/site-packages/nest/__init__.py", line 70, in <module> from . import pynestkernel as _kernel # noqa ImportError: dynamic module does not define module export function (PyInit_pynestkernel) " I tried nest 2.16.0, nest 2.20.0, and nest 2.18.0, but all encountered this error. I haven't encountered it before, so I would like to ask for advice on how to do it
Hi,
Can you give me a few more insights: What operating system are you using? Are you using any form of virtualization?
Python 2.7 has reached the end of its lifetime. NEST v3.6 is our most current release, which supports the latest versions of Python. We recommend using this.

Thank you very much for your reply. I downloaded the source code from Github and installed it on the Ubuntu system. My Python environment is 3.8.10. I also installed Nest3.3 and it ran successfully. Only Nest2. X series will have this issue。
Actually, there will be no errors during the installation process. After completing the environment configuration and testing in the Python environment, I will encounter this error when import Nest Python 3.8.10 (default, May 26 2023, 14:05:08) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information.

Hi
there may be a version mix-up of Python. It seems that you have built NEST with python 2.7, but you want to run it with python 3.8. This leads to problems. These old NEST versions do not support the latest python.
