Using CUDA 11.3 , PyTorch v1.7, Ubuntu 18.04.5 LTS. While executing:

python -m torch.distributed.launch --nproc_per_node=1 test_panoptic.py --meta metadata.bin --log_dir ~/logs config.ini seamseg_r50_vistas.tar images predictions

Given the following error. If anyone can provide help it will be much appreciated:
