Issue Details

Maybe stupid question to ask. I am getting to learn about tensorRT and came to this repo. Followed as mentioned in the installation procedures. I have TensorRT installed and export 'ed the PATH. After cmake, when make I get the following error.

Error Log

The problem is solved by symlink to the TensorRT lib directory as below: sudo ln -s /path_to_directory/TensorRT-8.6.1.6/lib/libnvinfer.so.8.6.1 /usr/lib/libnvinfer.so sudo ln -s /path_to_directory/TensorRT-8.6.1.6/lib/libnvonnxparser.so.8.6.1 /usr/lib/libnvonnxparser.so sudo ln -s /path_to_directory/TensorRT-8.6.1.6/lib/libnvinfer_plugin.so.8.6.1 /usr/lib/libnvinfer_plugin.so
