Can not import nglview although successfully installed it?

You can try

python -m ipykernel install --user

Then in your Jupyter notebook, choose the right kernel. If you are using python 2, make sure to choose Python 2 kernel.

widget not shown?

try

conda install traitlets=4.2.1 ipywidgets==4.1.1 notebook=4.1.0

supposed you created ipywidgets5 conda env to test, then if you want to go back to root env

source deactivate ipywidgets5

need to re-enable ipykernel

python -m ipykernel install --user

Can I have two MDA.Atomgroups in the same view?
