use_libuv was requested but PyTorch was build without libuv support

[zhaochenmeng]

When running sam2.1 training, the training code is: python training/train.py -c configs/train.yaml --use-cluster 0 --num-gpus 1, and the problem occurs hydra.errors.InstantiationException: Error in call to target ' training.trainer.Trainer':
RuntimeError('use_libuv was requested but PyTorch was build without libuv support')
full_key: trainer 。 What is libuv？

I am having the same issue. Is there any update?

hey i was facing similar issues and this seemed to work for me by downgrading PyTorch to version 2.3.x

Using pip install torch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0 --index-url https://download.pytorch.org/whl/cu118

Hope this helps!
