"No processes were matched" after set parameter KINETO_DAEMON_INIT_DELAY_S

[KepingYan]

Test script: scripts/pytorch/linear_model_example.py If I run it with command KINETO_USE_DAEMON=1 python3 scripts/pytorch/linear_model_example.py, I will meet this error as described in docs manifests as a segfault. Then I add parameter KINETO_DAEMON_INIT_DELAY_S to run this script KINETO_USE_DAEMON=1 KINETO_DAEMON_INIT_DELAY_S=3 python3 scripts/pytorch/linear_model_example.py, but the trace file won't be generated as expected.
