Operating system: windows10  
Slicer version: Slicer 4.11.0-2020-06-09  
Expected behavior: importation of ipywidgets module  
Actual behavior: ModuleNotFoundError

I have opened the Jupyter Notebook from my virtual environment, where the ipywidgets module (as the rest of the modules) has been installed.  
Unlike in a python kernel (where I can use ipywidgets), it seems to be not available in the Slicer kernel.

When I was installing the Slicer kernel, I followed [https://github.com/Slicer/SlicerJupyter/blob/master/README.md#setup](https://github.com/Slicer/SlicerJupyter/blob/master/README.md#setup) and double-checked with [https://ipywidgets.readthedocs.io/en/latest/user\_install.html](https://ipywidgets.readthedocs.io/en/latest/user_install.html) whether I missed anything for ipywidgets installation.

Should I install something in a different place other than my virtual environment?

You need to install ipywidgets in both 3D Slicer’s Python console and in the external Python environment.

How do you install ipywidgets in 3D Slicer’s Python console?
