/home/ub2004/anaconda3/envs/gh_deepspeed/lib/python3.11/site-packages/torch/distributed/launch.py:180: FutureWarning: The module torch.distributed.launch is deprecated
and will be removed in future. Use torchrun.
Note that --use_env is set by default in torchrun.
If your script expects --local_rank argument to be set, please
change it to read from os.environ['LOCAL_RANK'] instead. See

AttributeError: 'NoneType' object has no attribute 'get'

Start by reproducing the command in the issue, including torch.distributed.launch, run_clm_no_trainer.py, and config/ds_config_gpt_base_random_ltd.json. Trace the launcher's redirects handling to determine why to_map receives None, then verify the example can start without this AttributeError and document the required invocation or configuration.
