How to use HuggingFaceH4/zephyr-7b-alpha with Transformers:
# Use a pipeline as a high-level helper from transformers import pipeline pipe = pipeline("text-generation", model="HuggingFaceH4/zephyr-7b-alpha") messages = [ {"role": "user", "content": "Who are you?"}, ] pipe(messages)# Load model directly from transformers import AutoTokenizer, AutoModelForCausalLM tokenizer = AutoTokenizer.from_pretrained("HuggingFaceH4/zephyr-7b-alpha") model = AutoModelForCausalLM.from_pretrained("HuggingFaceH4/zephyr-7b-alpha") messages = [ {"role": "user", "content": "Who are you?"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, tokenize=True, return_dict=True, return_tensors="pt", ).to(model.device) outputs = model.generate(**inputs, max_new_tokens=40) print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:])) - Inference

How to use HuggingFaceH4/zephyr-7b-alpha with Docker Model Runner:
docker model run hf.co/HuggingFaceH4/zephyr-7b-alpha
Add chat template
Note, according to the model publisher, a "</s>" token was not used in the training, so I think this is incorrect. See the format the author described here:
https://huggingface.co/HuggingFaceH4/zephyr-7b-beta/discussions/7
Furthermore, the author had this note about the trailing token. See the author's comment in the link above:
---------------- BEGIN COMMENT IN LINK ABOVE ------------------
I had problems making the model stop generating content. So I found the solution in this link (https://medium.com/@parikshitsaikia1619/mistral-mastery-fine-tuning-fast-inference-guide-62e163198b06)
This change before starting the training solved my problem
tokenizer = AutoTokenizer.from_pretrained("HuggingFaceH4/zephyr-7b-beta")
#tokenizer.pad_token = tokenizer.eos_token
tokenizer.pad_token = tokenizer.unk_token <----
tokenizer.padding_side = "right" <----

Any help is greatly appreciated. Thank you!
