+Run the GUI from a **local Python installation** ([Installation](installation.md) — pip, conda, or a virtualenv on your workstation or cluster login node). Apptainer/Singularity and Docker images are intended for the **CLI** pipeline on HPC; running `partinet gui` inside a container is possible but not recommended.

+A local install avoids extra bind-mount and cache setup (`--no-home`, Hugging Face theme cache), keeps Slurm tools (`sbatch`, `scancel`) on the host PATH, and makes SSH port forwarding straightforward. On HPC, use the GUI locally on the login node and submit compute-heavy work via **Slurm**

-| | GUI | CLI |
-|---|---|---|
-| Audience | Beginners, interactive exploration | Experienced users, scripting, HPC |
-| Log output | Streamed live in the browser | Terminal / log file |
-| Threshold tuning | Interactive slider with live preview | Set once at run time |
-| Automation | Slurm submission from GUI | Fully scriptable |
-| HPC | Login-node GUI + Slurm batch jobs | Apptainer / Docker / modules |
