Notebook Kernel Resets and State Loss

Kernel resets wipe state and break long-running work. Persistent sessions avoid the reset spiral.

When a notebook kernel resets, state is gone. That makes long-running or stateful work fragile and expensive to repeat.

Why kernel resets hurt

  • you lose in-memory state,
  • outputs no longer match the current state,
  • reruns are the default recovery path.

The continuity alternative

A persistent terminal session keeps state alive across time, and output replay lets you recover the timeline without a full rerun.
