🚀 Quick Start

1. Installation

pip install datasets

2. Load Dataset

from datasets import load_dataset

# Load dataset (streaming recommended if storage is limited)
dataset = load_dataset("USERNAME/PanoCity", streaming=True)

# Iterate through samples
for sample in dataset["train"]:
    rgb_image = sample["rgb"]      # PIL Image
    depth_map = sample["depth"]    # PIL Image
    pose = sample["pose"]          # dict with transformation_matrix
    break
