fail to train BakedSDF

[tachoi]

According to '#50', BakedSDF trained using this command "ns-train bakedsdf --vis wandb --experiment-name garden-bakedsdf mipnerf360-data --data data/nerfstudio-data-mipnerf360/garden".
But, I got this error: FileNotFoundError: [Errno 2] No such file or directory: 'data/nerfstudio-data-mipnerf360/garden/transforms.json' and here transforms.json file does not exist.
What kind of data set can I use to tran BakedSDF?
