Hi, I noticed something odd when trying to run the Poisson iTutorial in Jupyter on a Windows machine.
The notebook hangs executing the first Python command after importing the netgen.gui. No errors are reported in the jupyter console window. This is using the latest build and Python 3.7.9 (not Anaconda)
import netgen.gui line is moved to the end of the notebook, then each cell computes quickly, and the mesh and solution can be displayed in the Netgen GUI – so we have a workaround. Also the webgui works fine.
