Hi
import animatplot as amp
Because I had originally installed SageMath using the bin file sage-9.0-Ubuntu_18.04-x86_64.tar.bz2
I suppose that in order to have the animatplot library in Sagemath Jupyter notebook, I must re-install Sagemath from source ? (I tried without success with the command :pip install animatplot without any error during the animatplot install process, but the library was still unknown in sagemath Jupyter notebook) .
