Summary

This model was trained using H2O LLM Studio.

Base model: google/gemma-2b

Usage

To use the model with the transformers library on a machine with GPUs, first make sure you have the transformers library installed.

pip install transformers==4.40.2

Also make sure you are providing your huggingface token to the pipeline if the model is lying in a private repo.

Either leave token=True in the pipeline and login to hugginface_hub by running

python

import huggingface_hub
huggingface_hub.login(<ACCESS_TOKEN>)

Or directly pass your <ACCESS_TOKEN> to token in the pipeline

python

from transformers import pipeline

generate_text = pipeline(
    model="yifanxie/magenta-swine-1",
    torch_dtype="auto",
    trust_remote_code=True,
    use_fast=True,
    device_map={"": "cuda:0"},
    token=True,
)

# generate configuration can be modified to your needs
# generate_text.model.generation_config.min_new_tokens = 2
# generate_text.model.generation_config.max_new_tokens = 256
# generate_text.model.generation_config.do_sample = False
# generate_text.model.generation_config.num_beams = 1
# generate_text.model.generation_config.temperature = float(0.0)
# generate_text.model.generation_config.repetition_penalty = float(1.0)

messages = [
    {
        "role": "system",
        "content": "You are a friendly and polite chatbot.",
    },
    {"role": "user", "content": "Hi, how are you?"},
    {"role": "assistant", "content": "I'm doing great, how about you?"},
    {"role": "user", "content": "Why is drinking water so healthy?"},
]

res = generate_text(
    messages,
    renormalize_logits=True
)
print(res[0]["generated_text"][-1]['content'])

You can print a sample prompt after applying chat template to see how it is feed to the tokenizer:

python

print(generate_text.tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
))

You may also construct the pipeline from the loaded model and tokenizer yourself and consider the preprocessing steps:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "yifanxie/magenta-swine-1"  # either local folder or huggingface model name
# Important: The prompt needs to be in the same format the model was trained with.
# You can find an example prompt in the experiment logs.
messages = [
    {
        "role": "system",
        "content": "You are a friendly and polite chatbot.",
    },
    {"role": "user", "content": "Hi, how are you?"},
    {"role": "assistant", "content": "I'm doing great, how about you?"},
    {"role": "user", "content": "Why is drinking water so healthy?"},
]

tokenizer = AutoTokenizer.from_pretrained(
    model_name,
    use_fast=True,
    trust_remote_code=True,
)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map={"": "cuda:0"},
    trust_remote_code=True,
)
model.cuda().eval()

# generate configuration can be modified to your needs
# model.generation_config.min_new_tokens = 2
# model.generation_config.max_new_tokens = 256
# model.generation_config.do_sample = False
# model.generation_config.num_beams = 1
# model.generation_config.temperature = float(0.0)
# model.generation_config.repetition_penalty = float(1.0)

inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt",
    return_dict=True,
).to("cuda")

tokens = model.generate(
    input_ids=inputs["input_ids"],
    attention_mask=inputs["attention_mask"],
    renormalize_logits=True
)[0]

tokens = tokens[inputs["input_ids"].shape[1]:]
answer = tokenizer.decode(tokens, skip_special_tokens=True)
print(answer)

Quantization and sharding

You can load the models using quantization by specifying load_in_8bit=True or load_in_4bit=True. Also, sharding on multiple GPUs is possible by setting device_map=auto.
