## Description

error while loading shared libraries: libnvinfer.so.7: cannot open shared object file: No such file or directory

This is the error I’m getting while trying to run Tensorrt sample code.  
The libraries are all mapped, which I checked using ldd command.

hi @ayckulwe,  
Request you to use [TRT NGC](https://ngc.nvidia.com/catalog/containers?orderBy=modifiedDESC&query=tens&quickFilter=containers&filters=) containers to avoid system dependencies related issues.  
Please follow the below link for reference to run the sampleOnnxMNIST.  
[https://github.com/NVIDIA/TensorRT/tree/master/samples/opensource/sampleOnnxMNIST#running-the-sample](https://github.com/NVIDIA/TensorRT/tree/master/samples/opensource/sampleOnnxMNIST#running-the-sample)

Thanks!

Thanks for the quick reply but I realized that I was using the wrong version of cudnn which was not compatible. I was using cudnn 8.0 for cuda 11.0 instead of cuda 10.2.

I have a similar error, the version I installed of cuda was 11.7 and cuDNN v8.7.0
