few files lost after fine-tuning

[huacilang]

Hello, the directory after fine-tuning only have few files ：adapter_config.json adapter_model.safetensors optimizer.pt preprocessor_config.json README.md rng_state.pth scheduler.pt trainer_state.json training_args.bin。
Missing a few files, such as pytorch_model.bin and config.json. What transformations have been applied?
thanks！
