Spyder (https://www.spyder-ide.org/) is a Python IDE and tool to run interactive Python applications in a GUI. Unfortunately we don't have a recipe for integration into the web portal. It can be installed by cluster users, however, and run from an interactive desktop session. Here are some instructions for how to set up Spyder.
mamba create -c conda-forge -n spyder-env spyder numpy scipy pandas matplotlib sympy cython
Once you have installed Spyder, you can start a “Remote desktop” environment on the Hábrók web portal. In this session you can open up a command line terminal window. In this window you can start Spyder using the commands:
mamba activate spyder-env spyder
This should start up the Spyder GUI.
