ImportError: libnvbufsurface.so.1.0.0: cannot open shared object file: No such file or directory

Hello, I am a student studying deepstream.
I installed deepstream-7.1_7.1.0-1_arm64 and tried to run Python code with devcontainer, but I got an error: libnvbufsurface.so.1.0.0 importerror.
find /usr /opt -type f -name ‘libnvbufsurface*.so*’ 2>/dev/null
When I run this command, it says the file doesn’t exist.
I think it might be a symbolic link issue, but I’m having trouble figuring it out.
What should I do?

1. Have you installed JetPack 6.1 according to the instruction in Installation — DeepStream documentation?
2. The DeepStream 7.1 docker is in (DeepStream | NVIDIA NGC)
3. Can you share the docker command you used?

Thank you for your reply.
I installed Deepstream according to the instructions in this link.
I gave up on running it in Docker, installed pyenv to set up the environment, and ran the code, and it worked fine.
