Description
Hello, thank you for your great work.
I’m trying to run the model using python app.py, but I encounter the following error when loading the pretrained weights:
RuntimeError: Error(s) in loading state_dict for TOSS: Unexpected key(s) in state_dict: "cond_stage_model.transformer.text_model.embeddings.position_ids"
It seems that the checkpoint contains a key that is not expected by the current model implementation.
Could you please advise how to resolve this issue (e.g., required dependency versions or a recommended workaround)?
Thank you in advance for your help.

Research direction
Start by running python app.py and inspect the pretrained checkpoint loading path for the TOSS model. Compare the checkpoint's unexpected cond_stage_model.transformer.text_model.embeddings.position_ids key with the current model state dictionary and check the required dependency versions; done means the pretrained weights load without this error.
