Cannot install openmc--plotter using pip

Hi,

I am trying to install openmc–plotter on a Mac with M1 processors runing Ubuntu 22 Server ARM. OpenMC works fine but when I used ‘pip install openmc-plotter’ I got the following error:

Defaulting to user installation because normal site-packages is not writeable
Collecting openmc-plotter
Using cached openmc_plotter-0.3.1-py3-none-any.whl (92 kB)
Using cached openmc_plotter-0.2.0-py3-none-any.whl (86 kB)
Using cached openmc_plotter-0.1.1-py3-none-any.whl (85 kB)
Requirement already satisfied: numpy in ./.local/lib/python3.10/site-packages (from openmc-plotter) (1.26.0)
ERROR: Cannot install openmc-plotter==0.1.1, openmc-plotter==0.2.0 and openmc-plotter==0.3.1 because these package versions have conflicting dependencies.

The conflict is caused by:
openmc-plotter 0.3.1 depends on PySide2
openmc-plotter 0.2.0 depends on PySide2
openmc-plotter 0.1.1 depends on PySide2

To fix this you could try to:

  1. loosen the range of package versions you’ve specified
  2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit Dependency Resolution - pip documentation v23.3.dev0

Some idea about the problem?
Thank you very much!

Looks like pyside2 can’t be installed. Sorry about that

Perhaps try pip installing from the repository develop branch

I just put in a PR to add insall instructions for the development branch to the readme file on the repo

But here is the command to try just in case that PR doesn’t get merged in

pip install git+https://github.com/openmc-dev/openmc.git@develop

The command

pip install git+https://github.com/openmc-dev/openmc.git@develop

seems to work but openmc-plotter is not installed (openmc-plotter: command not found)
