Fitrstly, thanks for your great work!
But when I want to run the in1k_vith14_ep300.yaml with the guidence, I have met a mistake:

File "/ijepa-main/main.py", line 52, in process_main
    app_main(args=params)
File "/ijepa-main/src/train.py", line 221, in main 
    encoder = DistributedDataParallel(encoder, static_graph=True)
RuntimeError: Default process group has not been initialized, please make sure to call init_process_group.

I have a device with two GPUs, both of which are RTX 3090. How could I solve this problem? If you can provide assistance, I would greatly appreciate it.

There's a Pull Request for some code that fixed this error for me. If you make the same changes to your source code you can start running.

Thank you for your assistance! After making changes to train.py, I was able to run the code successfully. I greatly appreciate your help.
