0.01s - Debugger warning: It seems that frozen modules are being used, which may  
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen\_modules=off  
0.00s - to python to disable frozen modules.  
0.00s - Note: Debugging will proceed. Set PYDEVD\_DISABLE\_FILE\_VALIDATION=1 to disable this validation.

this warning comes up when starting a notebook from terminal, though the notebook functios OK, but it feels annoying to see. Is this even an error to worry or not?  
and where to pass (Please pass -Xfrozen\_modules=off  
0.00s - to python to disable frozen modules.)?  
will this go away on its own in future updates or we need to do something about it?
