Hi @Wangzzy52,

This is most likely some sort of issue with your computing environment. Can you share more details regarding your computing environment (e.g., operating system, amount of RAM you have, number of CPUs)?

If you're on Linux, you can easily check how much CPU resources and RAM you're using with top, or alternatively free -g to focus on just RAM in gigabyetes (-g), and CPU information with lscpu.

This issue seems inactive, so I'll go ahead and close it. Hopefully you were able to figure this out in your computing environment @Wangzzy52.
