Bug! After resuming training, the info line doesn't show details anymore ...

[tjoymeed]

As you can see, after resuming from training, the [INFO:swift] line got disappeared with only blanks "--------------------"

All I did was adding this line in the training script:

--resume_from_checkpoint /myprojects/ms-swift/output/Qwen2.5-7B-32GPUs/v3-20250423-132415/checkpoint-400

Nothing else.

What's wrong?

Could anybody please help me?

Thanks a lot!

--load_args true

The problem is when I do --resume_from_checkpoint,

all the parameters in the training sh script file are kept the same as the previous training runs, except only for the "--resume_from_checkpoint".

So why do I need to "load_args" explicitly?

Also, in the manual, it says when training it should be "False".

Thanks a lot!

If you only add the parameter resume_from_checkpoint and do not delete other parameters, there is no need to add load_args.
In addition, the latest main branch does not reproduce the above problem, the [INFO:swift] line got disappeared with only blanks "--------------------".

The training script is as follows, only the parameter resume_from_checkpoint is added to the original training script.
