2. **Better Initialization**: Pre-trained weights provide excellent starting point, avoiding random initialization
3. **Regularization Effect**: Pre-trained features act as a strong regularizer, preventing overfitting
4. **Transfer Learning**: Features learned on diverse datasets transfer well to specific domains
**π Small Dataset Training Strategy:**
- **Use smaller DINO variants** (ViT-S/16, ViT-B/16) for better generalization
- **Single integration** provides optimal stability
- **Fewer epochs** (50-100) with **early stopping** based on validation loss
- **Lower learning rates** (1e-4 to 1e-5) for fine-tuning
- **Strong data augmentation** to maximize limited dataset usage
**β οΈ Important Notes:**
- Always use **`--integration single`** for datasets <2000 images
- **Freeze DINO weights** initially (default) for stability
- Consider **`--unfreeze-dino`** only after 20-30 epochs if performance plateaus
- Monitor **validation mAP** closely to prevent overfitting

Abstract
Enhancing the network architecture of the YOLO framework has been crucial for a long time but has focused on CNN-based improvements despite the proven superiority of attention mechanisms in modeling capabilities. This is because attention-based models cannot match the speed of CNN-based models. This paper proposes an attention-centric YOLO framework, namely YOLOv12, that matches the speed of previous CNN-based ones while harnessing the performance benefits of attention mechanisms.
YOLOv12 surpasses all popular real-time object detectors in accuracy with competitive speed. For example, YOLOv12-N achieves 40.6% mAP with an inference latency of 1.64 ms on a T4 GPU, outperforming advanced YOLOv10-N / YOLOv11-N by 2.1%/1.2% mAP with a comparable speed. This advantage extends to other model scales. YOLOv12 also surpasses end-to-end real-time detectors that improve DETR, such as RT-DETR / RT-DETRv2: YOLOv12-S beats RT-DETR-R18 / RT-DETRv2-R18 while running 42% faster, using only 36% of the computation and 45% of the parameters.

# β
Continue training with different configuration
python train_yolov12_dino.py \
--data /path/to/your/data.yaml \
--yolo-size l \
--pretrain /Users/Downloads/checkpoint.pt \
--epochs 200 \
--batch-size 8 \
--name resumed_training
```
### π **Resume Training from Checkpoint - ENHANCED: `train_resume.py`**
Use the **enhanced** `train_resume.py` script for **EXACT training state restoration** - training continues exactly where it left off:
```bash
# β
RECOMMENDED: Perfect state restoration (resumes with exact same loss values)
python train_resume.py \
--checkpoint /path/to/your/checkpoint.pt \
--epochs 400 \
--device 0,1
# β
Resume with different dataset (keeps all other settings identical)
python train_resume.py \
--checkpoint /workspace/DINOV3-YOLOV12/runs/detect/high_performance_p3p46/weights/last.pt \
--data coco.yaml \
--epochs 200 \
--batch-size 32 \
--name resumed_training \
--device 0,1
# β
Resume for fine-tuning (only change specific parameters)
python train_resume.py \
--checkpoint /Users/model_weight/diloyolo12_coco/last-2.pt \
--epochs 100 \
--unfreeze-dino \
--name fine_tuned_training
```
**π― ENHANCED Features of `train_resume.py` (v2.0):**
- **π― EXACT State Restoration**: Training starts with **identical loss values** as checkpoint's final step
- **π Perfect LR Continuity**: Uses exact final learning rate (0.00012475) - no more 4x loss spikes
- **β‘ 61 Hyperparameters**: Extracts and applies ALL training settings (momentum, weight decay, data augmentation, etc.)
- **π Full Auto-Detection**: Dataset, architecture, DINO configuration, optimizer state
- **𧬠Smart DINO Handling**: Automatic DINO layer freezing, AMP disabling, architecture matching
- **π State Analysis**: Shows expected loss values and training progression details
- **πͺ Zero Configuration**: Just provide checkpoint path - everything else is automatic
### π― **Resume DINO Training from Checkpoint (Legacy Method)**
For manual control, you can still use the main training script, but you **MUST** specify the same DINO configuration:
```bash
# β
Resume DINO training - specify DINO arguments to match checkpoint
python train_yolov12_dino.py \
--data coco.yaml \
--yolo-size l \
--pretrain /workspace/DINOV3-YOLOV12/runs/detect/high_performance_p3p46/weights/last.pt \
--dinoversion 3 \
--dino-variant vitb16 \
--integration triple \
--epochs 400 \
--batch-size 60 \
--name cont_p3p4 \
--device 0,1
# β WRONG - will cause architecture mismatch
python train_yolov12_dino.py \
--data coco.yaml \
--yolo-size l \
--pretrain /path/to/dino_checkpoint.pt \
--epochs 400
# Missing DINO arguments causes pure YOLOv12 mode
```
**β οΈ Important:** When using the legacy method, always include the original DINO configuration (`--dinoversion`, `--dino-variant`, `--integration`) to prevent architecture conflicts.
### π― **Exact State Restoration - How It Works**
The enhanced `train_resume.py` provides **perfect training continuity** by restoring the exact training state:
#### **π State Extraction Example**
```
π― RESTORING EXACT TRAINING STATE
============================================================
π Complete Training State Extracted:
Last Epoch: 199
Best Fitness: 0.699
Training Updates: 50000
Final Learning Rate: 0.00012475
Expected Loss Values (training should start with these):
box_loss: 0.865870
cls_loss: 0.815450
dfl_loss: 1.100720
π§ EXTRACTING ALL HYPERPARAMETERS FROM CHECKPOINT
β
Extracted 61 hyperparameters from checkpoint
π EXACT LEARNING RATE RESTORATION:
Original lr0: 0.01
Final training LR: 0.00012475
Resume LR: 0.00012475 (EXACT same as last step)
π― Training will continue from EXACT same state!
```
#### **π Before vs After Enhancement**
| Aspect | β Before (Problem) | β
After (Enhanced) |
|:-------|:-------------------|:-------------------|
| **Loss Values** | 4x higher (3.66 vs 0.866) | **Identical** (0.866 β 0.866) |
| **Learning Rate** | Reset to 0.01 (80x shock) | **Exact** (0.00012475) |
| **Training State** | "Starting from scratch" | **Perfect continuity** |
| **Hyperparameters** | Default values used | **All 61 extracted** |
| **User Experience** | Frustrating loss spikes | **Seamless resumption** |
### π **Resume Training Comparison**
| Method | Auto-Detection | State Restoration | Data Required | DINO Config Required | Best For |
|:-------|:---------------|:------------------|:--------------|:-------------------|:---------|
| **`train_resume.py`** β
| **Full auto** | **EXACT** | β No | β No | **Recommended - Perfect Continuity** |
| **`train_yolov12_dino.py --pretrain`** | Manual | Partial | β
Yes | β
Yes | Manual control & custom settings |
### π **Quick Reference - Resume Training**
#### **π― The Simple Way (Recommended)**
```bash
# Just provide checkpoint - everything else is automatic!
python train_resume.py --checkpoint /path/to/checkpoint.pt --epochs 400 --device 0,1
```
#### **π What You'll See**
```
π― EXACT STATE RESTORATION:
Final Learning Rate: 0.00012475
Expected Loss Values:
box_loss: 0.865870 β Training starts HERE (not 4x higher!)
cls_loss: 0.815450
dfl_loss: 1.100720
β
Extracted 61 hyperparameters from checkpoint
π― Training will continue from EXACT same state!
```
#### **β
Success Indicators**
- β
Loss values start **exactly** as shown in "Expected Loss Values"
- β
Learning rate is **tiny** (e.g., 0.00012475, not 0.01)
- β
No "starting from scratch" behavior
- β
Smooth loss progression from first epoch
### πͺ **Key Differences**
| Parameter | Purpose | Input Type | Use Case |
|:----------|:--------|:-----------|:---------|
| `--dino-input` | Load custom DINO models | DINO backbone weights (.pth, .pt) | Enhanced vision features |
| `--pretrain` | Resume YOLO training | YOLO checkpoint (.pt) | Continue training from checkpoint |
| `--pretrainyolo` | Inject base YOLO weights into dualp0p3 models | YOLO backbone weights (.pt) | Start dualp0p3 runs with P4+ YOLO initialization |
> **Note:** `--pretrainyolo` is optimized for the `dualp0p3` integration (YOLOv12-L). The script automatically copies weights from layer P4 onward while keeping the DINO-enhanced P0βP3 pipeline untouched. Itβs ideal when you want a YOLO foundation but still train the DINO front end from scratch.
```bash
# DualP0P3 with partial YOLO pretraining (recommended for crack datasets)
python train_yolov12_dino.py \
--data crack.yaml \
--yolo-size l \
--dinoversion 3 \
--dino-variant vitb16 \
--integration dualp0p3 \
--pretrainyolo yolov12l.pt \
--epochs 200 \
--batch-size 8
```
### 𧬠**Standard DINOv3 Models**
```bash
# Standard ViT models with --dino-variant (alternative to --dino-input)
python train_yolov12_dino.py \
--data coco.yaml \
--yolo-size s \
--dinoversion 3 \
--dino-variant vitb16 \
--integration single \
--epochs 100
```

## π Hugging Face Authentication Setup
### **Why Authentication is Required**
DINOv3 models from Facebook Research are hosted on Hugging Face as **gated repositories**, requiring authentication to access.
### **Step-by-Step Token Setup**
1. **Create Hugging Face Account**: Visit [huggingface.co](https://huggingface.co) and sign up
2. **Generate Access Token**:
- Go to [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens)
- Click "New token"
- Give it a name (e.g., "dinov3-training")
3. **Set Required Permissions**:
```
Repositories:
β
Read access to contents of all repos under your personal namespace
β
Read access to contents of all public gated repos you can access
```
4. **Apply Token**:
```bash
# Method 1: Environment variable (recommended) β
FULLY SUPPORTED
export HUGGINGFACE_HUB_TOKEN="hf_your_token_here"
# The training script automatically detects and uses this token
# Method 2: Login command (interactive)
hf auth login
# Follow the interactive prompts:
# - Enter your token (input will not be visible)
# - Choose to add token as git credential (Y/n)
# - Token validation will be confirmed
```
**β
Token Detection**: The training script will show:
```
Using HUGGINGFACE_HUB_TOKEN: hf_xxxx...
```
If your token is properly detected.
5. **Verify Access**:
```bash
hf whoami
# Should show your username if authenticated correctly
```
### **Common Issues**
- β **401 Unauthorized**: Invalid or missing token
- β **Gated repo error**: Token lacks required permissions
- β
**Solution**: Recreate token with correct permissions above

## β‘ **Advanced Training Options**
### π₯ **DINO Weight Control: `--unfreeze-dino`**
By default, DINO weights are **FROZEN** βοΈ for optimal training efficiency. Use `--unfreeze-dino` to make DINO weights trainable for advanced fine-tuning:
```bash
# Default behavior (Recommended) - DINO weights are FROZEN
python train_yolov12_dino.py \
--data coco.yaml \
--yolo-size s \
--dino-variant vitb16 \
--integration single \
--epochs 100
# Advanced: Make DINO weights TRAINABLE for fine-tuning
python train_yolov12_dino.py \
--data coco.yaml \
--yolo-size s \
--dino-variant vitb16 \
--integration single \
--unfreeze-dino \
--epochs 100
```
#### **π― Weight Control Strategy Guide**
| Configuration | DINO Weights | VRAM Usage | Training Speed | Best For |
|:--------------|:-------------|:-----------|:---------------|:---------|
| **Default (Frozen)** βοΈ | Fixed | π’ Lower | β‘ Faster | Production, general use |
| **`--unfreeze-dino`** π₯ | Trainable | π΄ Higher | π Slower | Research, specialized domains |
**β
Use Default (Frozen) when:**
- π **Fast training**: Optimal speed and efficiency
- πΎ **Limited VRAM**: Lower memory requirements
- π― **General use**: Most object detection tasks
- π **Production**: Stable, reliable training
**π₯ Use `--unfreeze-dino` when:**
- π¬ **Research**: Maximum model capacity
- π¨ **Domain adaptation**: Specialized datasets (medical, satellite, etc.)
- π **Large datasets**: Sufficient data for full fine-tuning
- π **Competition**: Squeeze every bit of performance

## β οΈ Troubleshooting: NaN Loss
### **If Training Shows NaN Loss:**
**Quick Fix - Choose One:**
**Option 1: Reduce Batch Size**
```bash
# If using batch 90 β try 45
--batch-size 45
# Still NaN? β try 24
--batch-size 24
# Still NaN? β try 16
--batch-size 16
```
**Option 2: Reduce Learning Rate**
```bash
# If using lr 0.01 β try 0.005
--lr 0.005
# Still NaN? β try 0.003
--lr 0.003
# Still NaN? β try 0.001
--lr 0.001
```
**Option 3: Both (Most Reliable)**
```bash
--batch-size 24 --lr 0.005
```
### **One-Line Rule:**
**NaN Loss = Reduce batch size by half OR reduce learning rate by half (or both)**
