restart kernel won't fix

Commencez par reproduire l’échec dans l’environnement VS Code Jupyter décrit par la trace de la pile, en utilisant le widget ipympl. Examinez les entrées de la pile WidgetManager.loadClass et handle_comm_open dans ipywidgets.js et ipywidgetsKernel.js, puis comparez les versions installées de Jupyter, du renderer et du widget. C’est terminé lorsque le déclencheur a été identifié et qu’il a été confirmé que l’erreur JavaScript intermittente ne se produit plus.
