Code Review
This pull request introduces a new test script for one-step off-policy training on NPU devices. The script focuses on the FSDP2 strategy. While the addition of NPU-specific testing is valuable, there are inconsistencies in the script's configuration and a lack of comprehensive testing for both FSDP2 and Megatron backends as implied by the script's comments.

trainer.device param will be automatically determined on Ascend NPU, maybe this param is not required?

Now ACTOR_STRATEGY is only used for some prints, can we set this param with $ACTOR_STRATEGY?

looks not necessary, can we remove it ?
Removed NUM_GPUS variable and updated echo statement to reflect current GPU settings.
