./main: error while loading shared libraries

[ontheway16]

I am on the path of training of custom data, I have successfully generated yolov4.wts from custom .weights file, run ./main, generated the .engine and tested the client.py without problems. This was for 100th epoch (normally, no objects detected), so after training reach to 1000th, followed the whole path to regenerate .engine for 1000th epoch weights.

But now, when I run ./main its now reporting an error;

(yolov4-triton) qgs@qgs-MS-7A74:~/yolov4-triton-tensorrt/build$ ./main
./main: error while loading shared libraries: libnvinfer.so.7: cannot open shared object file: No such file or directory

This has happened before and I have deleted local repo and re-cloned your repo, started from scratch (make etc) to make it function. What I am doing wrong here ? ( I am not running the ./main from inside docker). This is whats available in the folder:

You can't run a binary linked against shared libs from your container on your host if those libraries are not installed on your host. Install all dependencies and compile on your host to run on host or just run inside docker like described in the README.
