  * bash Anaconda3-2021.11-Linux-x86_64.sh

  * création d'un lanceur pour Anaconda Navigator : [[https://askubuntu.com/questions/1017284/cant-create-anaconda-shortcut-to-launch-from-desktop-on-ubuntu-17-10|Can't create anaconda shortcut to launch from desktop on ubuntu 17.10?]]
    * dans ~/bin, créer le fichier anaconda.sh

<code anaconda.sh>
export CONDA_PYTHON_EXE=/home/username/anaconda3/bin/python
export PATH=/home/username/anaconda3/bin:$PATH
python /home/username/anaconda3/bin/anaconda-navigator
</code>

    * créer un fichier anaconda.desktop 
<code anaconda.desktop>
[Desktop Entry]
Version=1.0
Type=Application
Name=Anaconda-Navigator
GenericName=Anaconda
Exec=/bin/bash "/home/username/bin/anaconda.sh"
Icon=/home/username/anaconda3/lib/python3.8/site-packages/anaconda_navigator/static/images/anaconda-icon-256x256.png

    * enable_high_dpi_scaling = False (pour évitre de trop gros lanceurs)
    * "channels" → ajouter à "default" le canal "conda-forge"
  * Spyder
    * thème clair : Idle,...
    * menu Outils - option Préférences - rubrique Console Ipython - onglet Graphiques - la sortie “Automatique” permet d'obtenir les graphes dans une fenêtre interactive, sinon, choisir “En ligne”. L'option sera prise en compte après avoir quitté Spyder et l'avoir relancé

  * conda update conda
  * conda update anaconda
    * mieux que conda update --all --yes : see [[https://github.com/conda/conda/issues/1414]]
