Python_apps can't run

I’am use “python3 deepstream_test_1.py /home/optical/deepstream_sdk_v4.0.1_x86_64/samples/streams/sample_1080p_h264.mp4” to run this example ,but it still stop in this step:

it is keep this status,and i can,t use CTRL+C to quit it.What should I do?Thanks.

Hi,
How long did you wait? Seems TensorRT in DeepStream was building the TensorRT engine, it needs take several minutes. Have you waited so long time?

Hi,I waited a little longer,it continue run.Thanks for your help!!!
