Tensorrt path

HI all,
I am working with tensorrt Ubuntu 20.04 and Nvidia 1650
I installed tensorrt by pip install nvidia-tensorrt and it is successful.
I can import tensorrt but I can not find the tensorrt ( trtexec ) path. I searched for that and find that it is usually at /usr/src/tensorrt or opt/ … but i can’t find the path. I aslo tried “find / -name tensorrt”, but i can not have the answer.

So, how can i do next and how can i install tensorrt properly ?
