Implemented Algorithms

Supervised Fine-tuning (SFT)

Fine-tune language models on supervised datasets with support for:

• Single-node and multi-node distributed training
• Configurable training parameters (epochs, batch size, learning rate, etc.)
• InstructLab-Training backend integration

from training_hub import sft

result = sft(
    model_path="/path/to/model",
    data_path="/path/to/data",
    ckpt_output_dir="/path/to/checkpoints",
    num_epochs=3,
    learning_rate=1e-5
)

Orthogonal Subspace Fine-Tuning (OSFT)

OSFT allows you to fine-tune models while controlling how much of its existing behavior to preserve. Currently we have support for:

• Single-node and multi-node distributed training
• Configurable training parameters (epochs, batch size, learning rate, etc.)
• RHAI Innovation Mini-Trainer backend integration

Here's a quick and minimal way to get started with OSFT:

from training_hub import osft

result = osft(
    model_path="/path/to/model",
    data_path="/path/to/data.jsonl", 
    ckpt_output_dir="/path/to/outputs",
    unfreeze_rank_ratio=0.25,
    effective_batch_size=16,
    max_tokens_per_gpu=2048,
    max_seq_len=1024,
    learning_rate=5e-6,
)

Installation

Basic Installation

pip install training-hub

Development Installation

git clone https://github.com/Red-Hat-AI-Innovation-Team/training_hub
cd training_hub
pip install -e .

CUDA Support

For GPU training with CUDA support:

pip install training-hub[cuda]
# or for development
pip install -e .[cuda]

Note: If you encounter build issues with flash-attn, install the base package first:

# Install base package (provides torch, packaging, wheel, ninja)
pip install training-hub
# Then install with CUDA extras
pip install training-hub[cuda]

# For development installation:
pip install -e .
pip install -e .[cuda]

For uv users: You may need the --no-build-isolation flag:

uv pip install training-hub
uv pip install training-hub[cuda] --no-build-isolation

# For development:
uv pip install -e .
uv pip install -e .[cuda] --no-build-isolation
