ModuleNotFoundError: No module named 'torch._custom_ops'; 'torch' is not a package

I follow the post to install Torch but got errors
PyTorch for Jetson

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
torchvision 0.16.0 requires torch==2.1.0, but you have torch 2.1.0a0+41361538.nv23.6 which is incompatible.

And got errors when using torch module

BRuntimeError: Couldn’t load custom C++ ops. This can happen if your PyTorch and torchvision versions are incompatible, or if you had errors while compiling torchvision from source. For further information on the compatible versions, check GitHub - pytorch/vision: Datasets, Transforms and Models specific to Computer Vision for the compatibility matrix. Please check your PyTorch version with torch.version and your torchvision version with torchvision.version and verify if they are compatible, and if not please reinstall torchvision so that it matches your PyTorch install.
