Summary

This model was trained using H2O LLM Studio.

Base model: EleutherAI/gpt-neox-20b
Dataset preparation: OpenAssistant/oasst1

Usage

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

bash

pip install transformers==4.28.1
pip install torch==2.0.0

python

import torch
from transformers import pipeline

generate_text = pipeline(
    model="h2oai/h2ogpt-gm-oasst1-en-1024-20b",
    torch_dtype=torch.float16,
    trust_remote_code=True,
    device_map={"": "cuda:0"},
)

res = generate_text(
    "Why is drinking water so healthy?",
    min_new_tokens=2,
    max_new_tokens=256,
    do_sample=False,
    num_beams=2,
    temperature=float(0.3),
    repetition_penalty=float(1.2),
)
print(res[0]["generated_text"])

You can print a sample prompt after the preprocessing step to see how it is feed to the tokenizer:

print(generate_text.preprocess("Why is drinking water so healthy?")["prompt_text"])

<|prompt|>Why is drinking water so healthy?<|endoftext|><|answer|>

Alternatively, if you prefer to not use trust_remote_code=True you can download h2oai_pipeline.py, store it alongside your notebook, and construct the pipeline yourself from the loaded model and tokenizer:

python

import torch
from h2oai_pipeline import H2OTextGenerationPipeline
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(
    "h2oai/h2ogpt-gm-oasst1-en-1024-20b",
    padding_side="left"
)
model = AutoModelForCausalLM.from_pretrained(
    "h2oai/h2ogpt-gm-oasst1-en-1024-20b",
    torch_dtype=torch.float16,
    device_map={"": "cuda:0"}
)
generate_text = H2OTextGenerationPipeline(model=model, tokenizer=tokenizer)

res = generate_text(
    "Why is drinking water so healthy?",
    min_new_tokens=2,
    max_new_tokens=256,
    do_sample=False,
    num_beams=2,
    temperature=float(0.3),
    repetition_penalty=float(1.2),
)
print(res[0]["generated_text"])

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 = "h2oai/h2ogpt-gm-oasst1-en-1024-20b"  # 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.
prompt = "<|prompt|>How are you?<|endoftext|><|answer|>"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)
model.cuda().eval()
inputs = tokenizer(prompt, return_tensors="pt", add_special_tokens=False).to("cuda")

# generate configuration can be modified to your needs
tokens = model.generate(
    **inputs,
    min_new_tokens=2,
    max_new_tokens=256,
    do_sample=False,
    num_beams=2,
    temperature=float(0.3),
    repetition_penalty=float(1.2),
)[0]

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