selgis 0.2.0

Universal Training Framework for PyTorch and HuggingFace Transformers

🛡️ Selgis ML

Autonomous Self-Healing Training Framework for PyTorch & Transformers.

Selgis (Self-Guided Intelligent Stability) is a library that turns unstable neural network training into a reliable, predictable process. It automatically detects Loss Spikes, NaN/Inf values, and plateaus, applying dynamic weight Rollback mechanisms and Learning Rate Surges to recover the run.

Especially effective for LoRA/QLoRA finetuning of LLMs (Llama, Qwen, Mistral) on consumer hardware, where standard trainers often crash with OutOfMemory errors or degrade due to fp16 instability.

🔥 Why Selgis?

Have you ever woken up in the morning to find your overnight run crashed with Loss: NaN at 80%? Or that the model "forgot" everything it learned due to a bad batch? Selgis solves this.

• 🛡️ Self-Healing Loop: Automatic rollback to the last stable state upon detecting anomalies (loss spikes / NaN).
• 🧠 Memory-Safe Architecture: State preservation logic tracks only trainable parameters (trainable-only). This allows training Qwen-4B / Llama-7B on cards with 8-12 GB VRAM without OOM during checkpoints.
• ⚡ Final Surge: If the model gets stuck on a plateau, Selgis can automatically boost the LR by 5-10x to break through local minima ("defibrillator effect").
• 📉 Smart Defaults: Built-in LR Finder and adaptive scheduler presets.

📊 Benchmarks

We tested Selgis under extreme conditions on real hardware (Tesla T4 16GB). Here are the results:

Task	Model	Problem	Selgis Solution	Result
LLM Finetuning	Qwen-2.5-4B (QLoRA)	OOM on 12GB cards + Loss Spike	Trainable-only state + Rollback	Memory: 8.2 GB, Loss < 0.001
Seq2Seq	LSTM (1.4M)	Catastrophic Spike (Acc 52% → 44%)	Rollback + Surge	+7% Accuracy (Recovered to 59.04%)
NLP	BERT-base	Instability on small batch (16)	Stable LR Finder	100.0% Accuracy (in 3 epochs)
CV	CNN (MNIST)	Overfitting & micro-spikes	Micro-rollbacks	99.09% (Held at generalization peak)

"Selgis doesn't just prevent explosions. It returns training to a productive track."

🛠️ Quick Start

1. Robust LLM Training (Llama / Qwen)

Selgis handles protection while you use the familiar Transformers API. Now with native BitsAndBytes quantization support.

from selgis import TransformerTrainer, TransformerConfig

# Configuration with native 4-bit quantization and protection
config = TransformerConfig(
    model_name_or_path="Qwen/Qwen-2.5-3B",
    
    # --- Native Quantization (New in v0.2.0) ---
    quantization_type="4bit", 
    bnb_4bit_compute_dtype="bfloat16",
    bnb_4bit_use_double_quant=True,
    
    # --- PEFT / LoRA ---
    use_peft=True,
    peft_config={
        "r": 16, 
        "target_modules": ["q_proj", "v_proj", "k_proj", "o_proj"]
    },
    
    # --- Selgis protection ---
    nan_recovery=True,      # Auto-rollback on NaN/Spike
    state_storage="disk"    # Save RAM (store state on disk)
)

# Start training (Trainer handles model loading and quantization automatically)
trainer = TransformerTrainer(model_or_path=config.model_name_or_path, config=config)
trainer.train() 
# You can go to sleep now. If the loss spikes, Selgis fixes it.

2. Standard PyTorch (Any Model)

from selgis import Trainer, SelgisConfig
import torch

# Your model
model = torch.nn.Sequential(
    torch.nn.Linear(10, 32),
    torch.nn.ReLU(),
    torch.nn.Linear(32, 2),
)

# Config
config = SelgisConfig(
    max_epochs=10,
    lr_finder_enabled=True,  # Auto-find optimal LR before start
    spike_threshold=3.0      # Rollback if loss jumps 3x
)

trainer = Trainer(
    model=model, 
    config=config, 
    train_dataloader=loader, 
    criterion=torch.nn.CrossEntropyLoss()
)
trainer.train()
