Container suffered a sudden massive existence failure: ContainerState.Exited

The container on which your execution runs can fail due to various issues. In some cases, it's due to malfunctioning hardware so simply rerunning the execution might help.

In some cases, a simple pip install is outputting a lot of progress % updates so frequently that it fills the buffer and eventually crashes the container. You can add --progress-bar=off to your pip install command to reduce the number of updates printed by pip.
