Which version of trlx and transformers are you using?

[PamKing7]

No matter whether I load the local model or the gpt2-imdb model from huggingface, the following error is reported:
ValueError: GPTModelBranch does not support an attention implementation through torch.nn.functional.scaled_dot_product_attention yet. Please request the support for this architecture: https://github.com/huggingface/transformers/issues/28005. If you believe this error is a bug, please open an issue in Transformers GitHub repository and load your model with the argumentattn_implementation="eager"meanwhile. Example:model = AutoModel.from_pretrained("openai/whisper-tiny", attn_implementation="eager")

This seems to be a problem caused by the version of transformers, but my version has been updated to the latest version.Which version of trlx and transformers are you using?

In addition, it appears that the TRLX module used for training does not support the MistralForCausalLM model.

I really admire you for completing a great job, however, I also encountered the same problem when I used colab to run your project. I have solved the problem after modifying transformers and sentence-transformer versions, but I have encountered new problems: RuntimeError: ffi_prep_cif_var failed, Could you please tell me all your environment versions?thank you！
