Process finished with exit code 137 (interrupted by signal 9: SIGKILL)

[erdemath]

I urgently need help with the following error message. I run pycharm on ubuntu 20.04.
I need to save data (as .npy) approximately 15 GB size. At the saving point, I always see
error message below;

Error:
Process finished with exit code 137 (interrupted by signal 9: SIGKILL) 

How to fix it?

This is an OOM (Out-Of-Memory).
The sigkill comes from the Kernel because it's out of free memory.

• buy more RAM
  
• use an iterative approach to process data in smaller chunks, which fits into RAM
  
• run your program once without PyCharm (PyCharm requires 1 GiB of RAM or more)
  
• incrase swap, but you're warned, it's deadly slow
  

The best method is to optimize your process, that it fits into memory.

[*]incrase swap, but you're warned, it's deadly slow

I expanded the virtual memory by doing this, and it worked. Here´s what I found here
