What are the mean/std for LSUN

Does anyone know what are the mean and std for LSUN dataset.
It would have been nice if the data loaders in pytorch had these values at time of construction of the data loader.

For instance if the dataloader would have the following args mean, std, normalize loaded by default.

MWE:

data = tv.datasets.LSUN(....)
loader = torch.utils.data.DataLoader(data, normalize=True)
loader.mean <--- print mean for dataset
loader.std <-- print std for dataset

The arg normalize=True would normalize the dataset by default no need to add it to transforms unless the user requires it by manually setting normalize=False, then s/he could pass whatever normalization they would like via the transforms.

Just a thought?
