I can not install Nest 3.3 simulator in Ubuntu 18.04

by salvatore.taffara＠phd.unict.it

Hi to the community, In order to install Nest 3.3 in Ubuntu 18.04 WITHOUTH the Docker, I followed two ways: 1) I downloaded the source zip file from "https://github.com/nest/nest-simulator/tags", then I followed the guide in "https://nest-simulator.readthedocs.io/en/v3.3/installation/linux_install.ht…", in particular the "Installation from source without a virtual Python environment" version. What I obtain is an error in the terminal: salvo@salvo-Aspire-GX-781:~/Downloads/nest-simulator-3.3-build$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/nest /home/salvo/Downloads/nest-simulator-3.3-build/ -- Host triple: x86_64-pc-linux -- Target triple: x86_64-pc-linux CMake Error at /usr/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find Python (missing: Python_INCLUDE_DIRS Python_LIBRARIES Development Development.Module Development.Embed) (found suitable version "3.8.13", minimum required is "3.8") Call Stack (most recent call first): /usr/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE) /usr/share/cmake-3.23/Modules/FindPython/Support.cmake:3192 (find_package_handle_standard_args) /usr/share/cmake-3.23/Modules/FindPython.cmake:519 (include) cmake/ProcessOptions.cmake:367 (find_package) CMakeLists.txt:129 (nest_process_with_python) -- Configuring incomplete, errors occurred! See also "/home/salvo/Downloads/nest-simulator-3.3-build/CMakeFiles/CMakeOutput.log". See also "/home/salvo/Downloads/nest-simulator-3.3-build/CMakeFiles/CMakeError.log". salvo@salvo-Aspire-GX-781:~/Downloads/nest-simulator-3.3-build$ 2) I also tried to force the following Ubuntu commands to obtain, from the ppa repository, the Nest version that I need (this is the ppa nest site: https://launchpad.net/~nest-simulator/+archive/ubuntu/nest): sudo add-apt-repository ppa:nest-simulator/nest sudo apt-get update sudo apt-get install nest=3.2-0~202202100714~ubuntu18.04.1 But is seems that the only package that is downloaded from this ppa is nest 2.20, in particular: 2.20.1-0~202103121402~ubuntu18.04.1. What can I do to install Nest 3.3 in my Ubuntu 18.04? Best, Salvo

Integration between ROS node and NEST

by salvatore.taffara＠phd.unict.it

Dear Nest community, I should import numerical data (not spiking data) obtained from a dynamic simulator called CoppeliaSim (ex VRep) into a Nest script. To do this I thought of using a ROS subscriber node that receives the data using a topic. I ask you, how do I interface Nest with Ros in order to import the data? Greetings, Except

Test NEST performance

by 512491013＠qq.com

Dear all, Recently, I've been trying to test NEST's performance(with and without MPI). But with PyNEST, it's hard to do more detailed testing with tools like Gprof. Only some print-time and memory methods can be inserted into the C++ source code for testing. Is there a C++ front-end interface that can call NEST C++ source code for testing? Of course, I used some of Python's performance testing tools, but only to the interface, not C++ in action. I'd appreciate any tips on how to test NEST's performance! Cong
