Hi @ngocnd2402.
This is a general error of Python on Windows.
We do not support Windows officially, but if you provide some more information, perhaps we could help.
Could you send information on the OS, relevant HW (GPU + CUDA), and Python environment?
Can you share the full error stack trace?

I have the same problem:
Windows Server 2022
Torch 1.13.0
Quadro P4000 GPU
Python 3.8
CUDA 12.0

I solve it by go to the file of the error and replace SIGKILL into SIGILL

from super-gradients.

@ngocnd2402 , does this solve your issue ?

from super-gradients.

yeah, it works. Thanks <3
