Dear experts,
I'd like to install the Nest version 2.20.0 instead of the last 3.1.
Is it still available for download?
Thanks

Dear Alberto,
the old releases are still
available<https://github.com/nest/nest-simulator/releases> on GitHub. This includes
v2.20.1<https://github.com/nest/nest-simulator/releases/tag/v2.20.1>.1>, which I would
recommend over 2.20.0, as it contains a fix for
#1394<https://github.com/nest/nest-simulator/issues/1394>, which could lead to wrong
simulation results under certain circumstances.
Cheers,
Jochen!

You will have to install the Python development libraries on your system
(sudoku apt-get , and/or use the CMake configuration option
-DPYTHON_INCLUDE_DIR to point to the folder containing it.
Lucky you, it is also a highly Google-able error: "missing Python.h" should
help you out!

OK, thanks,

the idea is to use python3.8, but seems it's going to use python2.7, is
this the possible issue?

I solved the issue before by changing the NEST_PYTHON_PREFIX with python3.8
path,
but now I am receiving another error and I dont know if the error is more
related to PyNN or still to nest installation
Thanks for any hints

Hi Alberto,
it looks like you're using a version of PyNN that does not support NEST
2.20. We'd recommend you upgrade to NEST 3, otherwise you'll have to
downgrade PyNN to a version that was written to support NEST2.20. PyNN is a
tool independent of NEST and we cannot support you further there.
Best of luck

I solved the issue before by changing the

python3.8 path,
but now I am receiving another error and I dont know if the error is more
related to PyNN or still to nest installation
Thanks for any hints

OK, thanks,
I have installed nest 2.20, but now having this issue related the calling
with pyNN
the idea is to use python3.8, but seems it's going to use python2.7, is
this the possible issue?
Thanks

You will have to install the Python development
libraries on your
system (sudoku apt-get , and/or use the CMake configuration option
-DPYTHON_INCLUDE_DIR to point to the folder containing it.
Lucky you, it is also a highly Google-able error: "missing Python.h"
should help you out!
