Bonjour
On a résolu le problème en installant jupyter lab au lieu du jupyter notebook dans le Dockerfile.
puis en activant l'env jupyter lab. https://github.com/SouthGreenPlatform/training_ONT_VM/blob/2021/Dockerfile
FROM jupyter/datascience-notebook
USER root
RUN apt update
RUN apt install -y python3-all-dev python3-pip python3-venv
RUN apt install -y python3-pyqt5 pyqt5-dev-tools qttools5-dev-tools
RUN pip install PyQt5 ete3 owlready2 pyproteinsExt ipympl jupyterlab
#Adding dedicated kernel
RUN python3 -m pip install --upgrade ipython
RUN python3 -m pip install bash_kernel
RUN python3 -m bash_kernel.install
ENV JUPYTER_ENABLE_LAB=yes
Merci
