Hi,

Have you run the script on another platform before?
If yes, which PyTorch version is used?

Thanks.

I want to run renet50 on my jetson agx orin 64G , when I install mmpretrain from source (skip conda) by https://mmpretrain.readthedocs.io/en/latest/index.html， it failed as ：

@qiangqiangsir the PyTorch 1.11 wheel was the last one to be built with USE_DISTRIBUTED:

PyTorch v1.11.0

If you require a newer version of PyTorch with distributed enabled, please see this thread for instructions on building PyTorch from source:

Or perhaps it’s possible to disable distributed mode in the mmpretrain library you are using?
