AssertionError: Unable to CreateHouse!

[KingxXxCode]

i am facing an issue tying to run the basic example.py scrip

`from procthor.generation import PROCTHOR10K_ROOM_SPEC_SAMPLER, HouseGenerator

house_generator = HouseGenerator(
split="train", seed=42, room_spec_sampler=PROCTHOR10K_ROOM_SPEC_SAMPLER
)
house, _ = house_generator.sample()
house.validate(house_generator.controller)

house.to_json("temp.json")
`
