Hi @yeh0102, we provide pre-built PyTorch wheels for the default version of Python that comes with Ubuntu, and on JetPack 5 / Ubuntu 20.04 that is Python 3.8 (on JetPack 4 / Ubuntu 18.04 that’s Python 3.6). So for Python 3.9 you would need to build it from source. There are build instructions in this thread that you can loosely follow: PyTorch for Jetson (you may still need to apply this patch)
