dataloader

from bevy_zeroverse_dataloader import BevyZeroverseDataset
from torch.utils.data import DataLoader

dataset = BevyZeroverseDataset(
    editor=False, headless=True, num_cameras=6,
    width=640, height=480, num_samples=1e6,
)
dataloader = DataLoader(
    dataset, batch_size=4, shuffle=True, num_workers=1,
)
