when I run these scripts,there're some questions

[Xie-PC]

Thanks to your sharing,but when i first run following codes in my docker containers './scripts/dist_train.sh 1 dev configs/stereo/kitti_models/liga.yaml' or './scripts/dist_test_ckpt.sh 1 ./configs/stereo/kitti_models/liga.yaml ./ckpt/pretrained_liga.pth' nothing to show! If I cancle this processing by ctrl+c, run it again that will show '''bash Traceback (most recent call last): File "tools/train.py", line 211, in main() File "tools/train.py", line 73, in main args.tcp_port, args.local_rank, backend='nccl' File "/root/LIGA-Stereo-master/liga/utils/common_utils.py", line 181, in init_dist_pytorch world_size=num_gpus File "/root/miniconda3/envs/liga/lib/python3.7/site-packages/torch/distributed/distributed_c10d.py", line 422, in init_process_group store, rank, world_size = next(rendezvous_iterator) File "/root/miniconda3/envs/liga/lib/python3.7/site-packages/torch/distributed/rendezvous.py", line 126, in _tcp_rendezvous_handler store = TCPStore(result.hostname, result.port, world_size, start_daemon, timeout) RuntimeError: Address already in use Traceback (most recent call last): File "/root/miniconda3/envs/liga/lib/python3.7/runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "/root/miniconda3/envs/liga/lib/python3.7/runpy.py", line 85, in _run_code exec(code, run_globals) File "/root/miniconda3/envs/liga/lib/python3.7/site-packages/torch/distributed/launch.py", line 261, in main() File "/root/miniconda3/envs/liga/lib/python3.7/site-packages/torch/distributed/launch.py", line 257, in main cmd=cmd) subprocess.CalledProcessError: Command '['/root/miniconda3/envs/liga/bin/python', '-u', 'tools/train.py', '--local_rank=0', '--launcher', 'pytorch', '--fix_random_seed', '--sync_bn', '--save_to_file', '--cfg_file', 'configs/stereo/kitti_models/liga.yaml', '--exp_name', 'dev']' returned non-zero exit status 1. ''' How should I solve it?

I met the same problem, and I solve it by change liga.yaml to liga.3d-and-bev.yaml. ./scripts/dist_train.sh 1 dev configs/stereo/kitti_models/liga.3d-and-bev.yaml

thanks for you reply, but what you say is useless for me, I still have this question.

The python program is not completely killed. Try to find the pid and kill (or killall python if you only run this python program.)

Hi, did you face any problems like "cannot import ** from mmcv.cnn"? I installed mmcv-full and mmdet. I also tried different versions of mmcv and mmdet, I didn't find one can run the test/train model. Any suggestions would be helpful. Thanks a lot!

@QingwuLiu-polymtl Could you show the complete error log? It should be good if you have installed mmcv-full instead of mmcv.
