• Fine-tuning dataset: zakariarada/oasst

Training

To train the model using your custom dataset, you can follow the steps below. This example demonstrates how to fine-tune the h2oai/h2o-danube3-500m-chat model using the Hugging Face transformers library.

Code Example

import pandas as pd
from transformers import (
    AutoTokenizer,
    AutoModelForCausalLM,
    TrainingArguments,
    Trainer
)
from datasets import Dataset

# Load Dataset
data_path = "train_full.pq"
df = pd.read_parquet(data_path)

# Prepare Dataset for Training
dataset = Dataset.from_pandas(df)

def preprocess_function(examples):
    # Combine 'instruction' and 'parent_id' as input prompt
    instruction = examples["instruction"]
    parent_id = examples["parent_id"]
    input_prompt = f"{parent_id}: {instruction}" if parent_id else instruction
    return {
        "input_text": input_prompt,
        "target_text": examples["output"]
    }

# Preprocess Dataset
dataset = dataset.map(preprocess_function, remove_columns=["id", "parent_id", "instruction", "output"])

# Load Tokenizer and Model
model_name = "h2oai/h2o-danube3-500m-chat"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Tokenize Data
def tokenize_function(examples):
    return tokenizer(
        examples["input_text"],
        padding="max_length",
        truncation=True,
        max_length=512
    )

tokenized_dataset = dataset.map(tokenize_function, batched=True)

# Training Arguments
training_args = TrainingArguments(
    output_dir="./output/TCLM-beta/",  # Directory to save model checkpoints
    num_train_epochs=3,  # Increase epochs for better fine-tuning results
    per_device_train_batch_size=4,  # Adjust based on GPU memory, increase if possible
    gradient_accumulation_steps=4,  # Accumulate gradients to simulate a larger batch size
    evaluation_strategy="steps",  # Evaluate more frequently for detailed tracking
    eval_steps=500,  # Evaluate every 500 steps to track progress without over-evaluating
    save_strategy="steps",  # Save checkpoints during training
    save_steps=500,  # Save model every 500 steps
    save_total_limit=2,  # Limit to the two best models to save disk space
    learning_rate=5e-5,  # Lower learning rate for fine-tuning
    weight_decay=0.01,  # Slight weight decay to prevent overfitting
    lr_scheduler_type="cosine",  # Cosine schedule for smoother learning rate decay
    warmup_ratio=0.06,  # Warmup to stabilize initial training
    logging_dir="./logs",  # Directory to save training logs
    logging_steps=50,  # Log progress every 50 steps for better monitoring
    fp16=True,  # Enable mixed precision for faster training with less memory
    load_best_model_at_end=True,  # Load the best model at the end based on evaluation metric
    metric_for_best_model="eval_loss",  # Use evaluation loss to determine the best model
    greater_is_better=False,  # Lower loss is better
)


# Trainer Setup
trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=tokenized_dataset,
    tokenizer=tokenizer,
)

# Train Model
trainer.train()

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==4.45.0

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

import huggingface_hub
huggingface_hub.login(<ACCESS_TOKEN>)

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

from transformers import pipeline

generate_text = pipeline(
    model="zakariarada/TCLM-beta",
    torch_dtype="auto",
    trust_remote_code=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": "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:

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:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "zakariarada/TCLM-beta"  # either local folder or Hugging Face 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": "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,
    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.
