Description
Since about a week, I notice the size of my checkpoints to differ significantly compared to previous runs. I am training the same model on the same data, only on another GPU (A100 80GB vs A100 40GB). Previously, the optimizer states were way larger than the model states, now it is inversed and the inference results are nonsense, in contrast to the results of previous runs. I have to clue what might cause this, is this a common problem?
ds_report output on the new GPU (same as on the old GPU):

Furthermore, the output folders do not contain a config.json anymore, which seems to be renamed to adapter_config.json
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by comparing the checkpoint contents and the presence or absence of config.json versus adapter_config.json across the two GPU runs, then verify the PyTorch and DeepSpeed environments against the reported ds_report output. Done means identifying a reproducible cause for the changed optimizer/model state sizes and incorrect inference results, with a confirmed explanation or fix.
