When kernels are culled, the kernel is terminated in the background, unbeknownst to the session management. As a result, invalid sessions can be produced that appear to exist, yet cannot produce a model from the persisted row due to the associated kernel no longer being active. Prior to this change, these sessions, when encountered via a subsequent call to `get_session()`, would be deleted and a KeyError would be raised. This change updates the existence check to tolerate those kinds of sessions. It removes such sessions (as would happen previously), but rather than raise a KeyError when attempting to convert the row to a dictionary, it logs a warning and returns None, which then allows `session_exists()` to return False since the session was removed (as was ultimately the case previously). Calls to `get_session()` remain just as before and have the potential to raise `KeyError` in such cases. The difference now being that the `KeyError` is accompanied by a message indicating the cause. Fixes #4209 |

Jupyter Notebook
The Jupyter notebook is a web-based notebook environment for interactive computing.
Jupyter notebook, the language-agnostic evolution of IPython notebook
Jupyter notebook is a language-agnostic HTML notebook application for Project Jupyter. In 2015, Jupyter notebook was released as a part of The Big Split™ of the IPython codebase. IPython 3 was the last major monolithic release containing both language-agnostic code, such as the IPython notebook, and language specific code, such as the IPython kernel for Python. As computing spans across many languages, Project Jupyter will continue to develop the language-agnostic Jupyter notebook in this repo and with the help of the community develop language specific kernels which are found in their own discrete repos.
