AGX orin with nccl

[zuyulong]

machine：
2 *Jetson AGX Orin 64GB

env：
Jetpack 5.1.1
Python 3.8.10
NCCL 2.11.4+cuda11.4
Pytorch v1.11.0

The pytorch i used is provided by NVIDIA；
PyTorch for Jetson
I try to build a distributed development environment based on AGX Orin, and communicate using nccl.
I’ve tried version 2.1 of pytorch in the past, But it doesn’t seem to provide a distribution module.

#pytorch v2.1.0

import pytorch
torch.distributed.is_available( )
False

Then i switched the version to v1.11.0, but i met the following problem:

#pytorch v1.11.0

import pytorch
torch.distributed.is_available( )
True
torch.distributed.is_nccl_available()
False
torch.cuda.nccl.is_available(torch.randn(1).cuda())
/usr/local/lib/python3.8/dist-packages/torch/cuda/nccl.py:15: UserWarning: PyTorch is not compiled with NCCL support
warnings.warn('PyTorch is not compiled with NCCL support')
False

I want to know dose the orin support NCCL? And how to solve the problem of use NCCL?Thanks!
