But now when I run import torch, an error occurs: ‘OSError: libmpi_cxx.so.40: cannot open shared object file: No such file or directory’.

Hi @yys9905a, when you tried torch-1.11.0-cp38-cp38-linux_aarch64.whl, did you install libopenmpi-dev from apt? Can you find the /usr/lib/aarch64-linux-gnu/libmpi_cxx.so.40 library installed?

You can also build PyTorch from source, like in the PyTorch for Jetson thread or like in this torch-builder dockerfile:
