Netgen gui is not opened in jupyter notebook

Dear all, 

I am new to Netgen/NGsolve. I have installed Netgen via Anaconda successfully. While I was testing the i-tutorials, I realized that Netgen Gui can't be opened automatically when I run the Jupyter notebook. It only shows "importing NGSolve-6.2.2301" without anything popping up. But it works when I use "Netgen poisson.py". 

Can anyone tell me how to fix it?

Many thanks,
Julie

Hi,
you can use "import netgen.gui" to open the interactive window.
That's how they did it in the versions of the notebooks that are on youtube (the first: ).
Hope that helps,
