When the SSH Tool Is Used to Connect to a Notebook Instance, Server Processes Are Cleared, but the GPU Usage Is Still 100%

This fault occurs because code execution is suspended and the GPU memory is not released. Alternatively, the program is cleared due to memory overflow during code execution. In this case, you need to release the GPU memory and restart the instance. To avoid unsaved code caused by the end of processes, you are advised to periodically save the code to an OBS bucket or the ./work directory of the container.
