Segmentation Fault installing PYNE-0.7-7

[Ron Lavera]

To all

I have been trying to use PYNE with OPENMC.

In the past (April 2023 time frame) I managed to get pyne to work in a WSL2 Ubuntu base environment. However, I was unable to get it to work with openmc.

Fast forward to the present, I have picked up again on this endeavor

I set up a conda env   conda activate openmc-env

I then installed openmc into that environment.

I tried to use Alex Malins' instructions for installing pyne.

I encounter a lot of problems with this section:

sudo apt install python3-pip build-essential cmake gfortran libblas-dev liblapack-dev libeigen3-dev libhdf5-dev hdf5-tools pip3 install --user numpy==1.17.4 scipy cython nose tables matplotlib future

and basically, I had to manually install scipy, cython, nose, tables matplotlib and future.

I am running WSL2  Ubuntu 22.04.2 LTS.

I am getting the following error message:

############### Begin Python Install ###############
-- Python installer:
  PYTHON_EXECUTABLE: /opt/anaconda3/3.10/anaconda3/envs/openmc-env/bin/python3
  CMAKE_INSTALL_PREFIX: /opt/anaconda3/3.10/anaconda3/envs/openmc-env

CMake Error at cmake/SetupSubPyInstall.cmake:15 (message):
  Process setup_sub.py install failed, res_var = 'Segmentation fault'
Call Stack (most recent call first):
  cmake_install.cmake:46 (include)

As an extra added bonus, the installation of pyne into the openmc-env broke my original installation of pyne in the base env, and now I don't have any functional version of pyne.

Your help would be appreciated.

Thanks

Ron

Hello Ron,

 

I’m sorry that you’re experiencing so many challenges.  We don’t have a lot of WSL experience on our team, but hopefully we can offer some guidance as a community.

 

If you are installing from source, you might try the newest Ubuntu installation script.  I can’t say how it works within a conda environment, as we test it on a clean Ubuntu system.

 

Regards,

Paul
