Image specs: Variable sizes, RGB

Example Usage

Below is a quick example of how to load this dataset via the Hugging Face Datasets library.

from datasets import load_dataset  

# Load the dataset  
dataset = load_dataset("../../aidatasets/images/cub200.py", split="train", trust_remote_code=True)
# dataset = load_dataset("../../aidatasets/images/cub200.py", split="test", trust_remote_code=True)  

# Access a sample from the dataset  
example = dataset[0]  
image = example["image"]  
label = example["label"]  

image.show()  # Display the image  
print(f"Label: {label}")
