Slicer and jupyter kernel dies repeatedly, problem with connection.

This explains it all. This is a third-generation Intel CPU, released more than 8 years ago.

When we choose software libraries and instruction set for building the binary packages we need to balance between backward compatibility and performance. If preserve backward compatibility with older systems then we cannot use new features and the software will run slower on modern systems. If we use latest features then the software will not run at all on older systems. Therefore, we aim for preserving backward compatibility with computers that are not older than 5 years.

You either need to upgrade your hardware or build Slicer yourself (on your system by default an older instruction set will be used that is compatible with your CPU, so you don’t need to tune any build options).

Thank you! Does this also explain why the setup on docker does not work?
