+Note the use of `--no-deps` in the final step. Indeed the `environment.yml` already instructs conda to install most necessary package dependencies. However, some packages (pyside2, gmsh, pyepr-quantum, and pyaedt) need to be installed manually via pip after the conda environment setup to avoid version conflicts. We therefore prevent `setup.py` from overwriting them with potentially incompatible packages.
 
 This creates a new environment with name `<env_name>` with all the necessary library dependencies.
 Then it activates the new environment.
