Error during single card multi-GPU detection task run.

[vittoria310]

I am having an issue while training detection model on a single card with two GPUs using the Coco data set. I am getting the following error:
subprocess.CalledProcessError: Command '['/home/data/env/bin/python', '-u', './train.py', '--local_rank=1', 'configs/mask_rcnn_efficientformerv2_s2_fpn_1x_coco.py', '--seed', '0', '--launcher', 'pytorch']' returned non-zero exit status 1.

Can you please help me understand why I am getting this error?

Thank you for your time and assistance.
