It’s saying it can find any of the files. What does pip3 show torch list as the install location for PyTorch? Track it down, run the ldd command that I did on it’s torch/_C.cpython-38-aarch64-linux-gnu.so file, and that will tell you which dependencies are missing.
Or if you are unfamiliar with doing these kind of things yourself, you can try the l4t-pytorch container that I linked to above.
