OPTPY 2025 - feedback and ideas

[WandrilleD]

• install issues: make a small testing script to give to students before the course
• install issues: in some version of jupyter-notebook/lab, cython annotations do not appear. Find the cause and possible solution
• more hand-holding in the exercises
• review the self-assessment quizz for relevance (should it be harsher?)
• I am unhappy with the flow of the multiprocessing part + it failed for some users. Solve technical issues and perhaps a flow that begins with success then caveats instead of failure then success
