diffusionLM 0.1.8

A diffusion-based language model implementation

DiffusionLM: Large Language Models with Diffusion

DiffusionLM is a novel approach to language modeling that combines transformer architectures with diffusion processes for high-quality text generation. This package provides a flexible and efficient implementation of diffusion-based language models.

Features

• Advanced Architecture

  • Transformer-based backbone with diffusion capabilities
  • Configurable model sizes (small, medium, large)
  • Time step conditioning
  • Attention mechanisms optimized for text

• Multiple Generation Strategies

  • Auto-regressive generation
  • Parallel generation
  • Confidence-based masking
  • Semi-autoregressive generation
  • Top-p (nucleus) sampling
  • Beam search

• Training Features

  • Distributed training support
  • Mixed precision training
  • Gradient checkpointing
  • Early stopping
  • Model checkpointing
  • Learning rate scheduling

• Utilities

  • Real-time token generation streaming
  • Model saving and loading
  • HuggingFace Hub integration
  • Comprehensive logging
  • Error handling

Installation

pip install diffusionLM

For development installation:

git clone https://github.com/codewithdark-git/PIP-DifffusionLM.git
cd PIP-DifffusionLM
pip install -e .

Quick Start

from diffusionLM.utils import prepare_dataset
from diffusionLM.model import DiffusionConfig, DiffusionLLM
from transformers import AutoTokenizer

# Load tokenizer and prepare dataset
tokenizer = AutoTokenizer.from_pretrained("gpt2")
train_dataset, val_dataset, _ = prepare_dataset(
    dataset_name="wikitext/wikitext-103-v1",
    tokenizer_name="gpt2"
)

# Initialize model
config = DiffusionConfig(
        vocab_size=len(tokenizer),
        max_position_embeddings=256,
        num_timesteps=50,
        pad_token_id=tokenizer.pad_token_id,
        mask_token_id=tokenizer.mask_token_id,
        # **config_kwargs
    )

model = DiffusionLLM(config)

Training

Basic Training

from diffusionLM import trainer

train_model = trainer(
        model=model,
        train_dataset=train_dataset,
        val_dataset=val_dataset,
        batch_size=batch_size,
        num_epochs=num_epochs,
        learning_rate=learning_rate,
        num_timesteps=num_timesteps,
        save_path=save_dir,
        device=device,
    )

Model Registry

from diffusionLM import registerANDpush

registerANDpush(
    model=trained_model,
    tokenizer=tokenizer,
    model_type="diffusionLM",
    repo_id="your-username/model-name"
)

Error Handling

The package includes comprehensive error handling:

from diffusionLM import DiffusionLMError, handle_errors

@handle_errors()
def your_function():
    # Your code here
    pass
