Thank you for the instructions. I have managed to start a new notebook with JupyterLab instead of Jupyter Notebooks. I installed visual debug extension and xeus-python jupyter labextension install @jupyterlab/debugger conda install xeus-python -c conda-forge. I also instaled conda and nodejs and npm as per instructions. However i didn’t have option to selectd xeus kernel notebook. At this moment that’s the only option to use visual debugger. Also i restarted (stopped and started) the notebook but i kind of lost conda by doing this, so couldn’t activate my environment. I must be making a lot of mistakes there. Any help will be much appreciated! thanks!
