Yes, just run following code from Jupyter env
import sys
!conda install --yes --prefix {sys.prefix} ipywidgets
Others, if installing from Jupyter env, please run with --yes --prefix {sys.prefix} to make sure it lands in correct environment.
If using pip, do
!{sys.executable} -m pip install ipywidgets
Not adding these prefixes is very often not enough if ran from Jupyter notebook.
