Thanks. The custom kernal for Jupyter works great.

However, considering my original question. If I follow the advice by TI23XPRO, I need to first create a project environment, then build a custom sysimage that is saved in the same project folder and then VSC is supposed to automatically find it. However, if I don’t want to create an environment and a custom sysimage of this environment (which might also include other packages), how to I tell VSC to consider the sysimage `sys_itensors.so` in my `.julia/sysimages` folder?
