[Bug] RuntimeError: Child process exited unsuccessfully with error code -6

[MehdiTantaoui-99]

I ran tuning on an ONNX file using python and tvmc API, but after reaching half of the tasks it throws an error which stops the tuning and makes you start from the beginning (happened multiple times)

 # Perform actual tuning with selected tasks
tvmc.tune(
    model,
    target=target,
    tuning_records=tuning_records,
    enable_autoscheduler=args.enable_autoscheduler,
    trials=args.tuning_trials,
    early_stopping=args.early_stopping,
    timeout=20,
)
print("Tuning completed.")
