Questions

Hi,
I used the code to continue pretrain the model and used zero3 for model training. But I found my checkpoint file zero_pp_rank_*_mp_rank_00_model_states.pt is empty, the file only has model parameters name and shape, don't have the weights. Have you ever met this problem and how to fix?

Thanks!

I have met the same problem and my solution is to use deepspeed zero2 instead of zero3

My solution is to save checkpoints by myself or you can use zero_to_fp32

@mynewstart I found my converted ckpt global_step_xxx only contains meaningful *optim_states.pt but only empty *model_states.pt. Any clues on this? Thanks.
