title: Jupyter Lab freezes the computer when out of RAM - how to prevent it?
body: <p>I have recently started using Jupyter Lab and my problem is that I work with quite large datasets (usually the dataset itself is approx. 1/4 of my computer RAM). After few transformations, saved as new Python objects, I tend to run out of memory. The issue is that when I'm approaching available RAM limit and perform any operation that needs another RAM space my computer freezes and the only way to fix it is to restart it. Is this a default behaviour in Jupyter Lab/Notebook or is it some settings I should set? Normally, I would expect the program to crash out (as in RStudio for example), not the whole computer </p>
