The "Loading an example dataset" in Readme doesn't work for https url

[omshinde]

What I tried -

import mlcroissant as mlc
url = "http://huggingface.co/api/datasets/fashion_mnist/croissant"
ds = mlc.Dataset(url)
metadata = ds.metadata.to_json()
print(f"{metadata['name']}: {metadata['description']}")
for x in ds.records(record_set="default"):
    print(x)

Output:
