ds_clf(text,max_new_tokens=128)when the model_id is “decapoda-research/llama-7b-hf” ,generate 128 news tokens about 6s, but when I replace the model_id with our own finetuning model, the inference time takes about 26s.Remarks：training：we are using sagemaker’s smp distributed training method - p4dinference：local test - p3.2xlargetransformers install:  pip install git+https://github.com/huggingface/transformers.gitI really need help!  I’ve tried every possible solution I could find, but nothing improves the inference speed

Did you manage to find a solution for this? I am also facing similar issue.

Based on my experience, Please check the model config file, and see ifuse_cache=True. When fine-tuning the model and save the model, theuse_cacheusually set toFalse. You can manually setuse_cache=Trueto make your model much faster. Thank you!
