Feb 17, 2021 · However, if your kernel were to support message-based interrupts, (which ipykernel does not) then the interrupt sent from jupyter_client would go through the messaging protocol and not via a signal (or interrupt_event) and would likely work. Always after a couple days of working in VS code notebooks and reputedly interrupting kernels, I suddenly get "Cannot run cells, as the kernel 'Python XXX' is dead" every time I try to interrupt a kernel. Due to the complexities involved in security software unfortunately many kernel-level anti-cheats, including BE, are not compatible with this feature yet. Often when I try to stop a cell execution, interrupting the kernel does not work. The interrupt handler must run quickly, because it's preventing any other interrupt from running.
