What causes the code below to get an error when installing openmc ?

tsania@tsaniaeksa:~/openmc$ cd …
tsania@tsaniaeksa:~$ pip3 install numpy

This looks like an issue with installing NumPy, not OpenMC. Are you planning to install OpenMC from source? If not, you can install OpenMC using conda/mamba and it should install numpy during the openmc installation so you don’t have to do a separate pip install of numpy.
