## Quick Start

### Basic Usage

```python
from datasets import load_dataset
from PIL import Image

# Load the dataset
dataset = load_dataset("leonelgv/pollinator-insects-dataset")

# Access different splits
train_data = dataset["train"]
val_data = dataset["validation"] 
test_data = dataset["test"]

# Load an example
example = train_data[0]
print(f"Species: {example['scientific_name']}")
print(f"Label: {example['label']}")
print(f"Family: {example['family']}")
print(f"Habitat: {example['habitat']}")
```

### Advanced Usage with PyTorch

```python
import torch
from torch.utils.data import DataLoader
from torchvision import transforms
from datasets import load_dataset
from PIL import Image

# Load dataset
dataset = load_dataset("leonelgv/pollinator-insects-dataset")

# Define transforms for training
train_transform = transforms.Compose([
    transforms.Resize((224, 224)),
    transforms.RandomHorizontalFlip(p=0.5),
    transforms.RandomRotation(degrees=15),
    transforms.ColorJitter(brightness=0.2, contrast=0.2),
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.485, 0.456, 0.406], 
                        std=[0.229, 0.224, 0.225])
])

class PollinatorDataset(torch.utils.data.Dataset):
    def __init__(self, hf_dataset, transform=None):
        self.dataset = hf_dataset
        self.transform = transform
    
    def __len__(self):
        return len(self.dataset)
    
    def __getitem__(self, idx):
        example = self.dataset[idx]
        
        # Load image (you'll need to handle the image loading based on your setup)
        image_path = example["image_path"]
        image = Image.open(image_path).convert("RGB")
        label = example["label"]
        
        if self.transform:
            image = self.transform(image)
        
        return image, label

# Create PyTorch datasets

train_loader = DataLoader(train_dataset, batch_size=32, shuffle=True)
```

### Usage with Transformers

```python
from transformers import AutoImageProcessor, AutoModelForImageClassification
from datasets import load_dataset

# Load dataset
dataset = load_dataset("leonelgv/pollinator-insects-dataset")

# Load pre-trained model
processor = AutoImageProcessor.from_pretrained("google/vit-base-patch16-224")
model = AutoModelForImageClassification.from_pretrained(
