Bootstrap : no socket interface found

[gitKincses]

Really useful work! However, I encountered the following issue while running the program:

(grootv) hqu@hqu-System-Product-Name:~/user/MambaTree-main$ bash GrootV/scripts/bash_cls_train.sh --data-path /home/hqu/2tb/datasets/imagenet/imagenet
/home/hqu/anaconda3/envs/grootv/lib/python3.9/site-packages/mmcv/__init__.py:20: UserWarning: On January 1, 2023, MMCV will release v2.0.0, in which it will remove components related to the training process and add a data transformation module. In addition, it will rename the package names mmcv to mmcv-lite and mmcv-full to mmcv. See https://github.com/open-mmlab/mmcv/blob/master/docs/en/compatibility.md for more details.

Is it possible that I missed specifying some parameters in my command line instruction? I haven't worked with these parameters before, so I’m not very clear on their purpose.
