Define the python version

[eulovi]

While trying to run Meshpy, I noticed that Meshpy is now using Python 3.12. In the Installation instructions, it is unclear if this Python version is used, since with python3 -m venv meshpy-env a python environment is created with the local Python3 version, which can be different from Python 3.12.
Should the installation instructions be updated?

It would be nice to just switch to a conda environment and maybe update the install instructions accordingly?

Something like

conda create -n meshpy python=3.12

conda activate meshpy

pip install -e .

Thanks for the suggestion. We should definitely adapt the script so it works with the main version of meshpy. @davidrudlstorfer I am against an installation instruction completely relying on conda. But maybe something like:

Installation

MeshPy is developed with python3.12. Other versions of Python might lead to issues. It is recommended to use a python environment container such as venv or conda.

• venv: Chose an appropriate directory for this, e.g., /home/user/opt. A virtual environment can be created with (make sure that python3 points to a python3.12

  python3 -m venv meshpy-env

  The created virtual environment can be loaded with

  source meshpy-env/bin/activate

• conda: A condo environment can be created with

  conda create -n meshpy python=3.12
  conda activate meshpy

From now on we assume that the previously created enviroment is loaded. To install meshpy go to the repository root directory

cd <path_to_meshpy>
