1. check the libcuda, libnvcuvid and libnvidia-encode found in the system. Remove them all except the one under /usr/lib/x86_64-linux-gnu which corresponds to nvidia-smi driver version, the non related one just remove

 

2. version tested as following:-

version 1:

gpu 3090, ubuntu18, nvidia-smi 455.32.00, /usr/lib/x86_64-linux-gnu/libcuda.so  /usr/lib/x86_64-linux-gnu/libcuda.so.1, /usr/lib/x86_64-linux-gnu/libcuda.so.455.32.00, /usr/local/cuda-11.0/lib64/libnvcuvid.so, /usr/local/cuda-11.0/lib64/libnvcuvid.so.455.32.00, /usr/local/cuda-11.0/lib64/libnvcuvid.so.1

 

version 2:
