Hi @jlambert,

Thanks for adding this. I notice that this function calls save_json_dict. Do you think that it might be convenient if we move directory creation into that function?

My thought is this: https://github.com/argoai/argoverse-api/blob/9ad7251e863590603c3f6064a45830dabd3a15e2/argoverse/utils/json_utils.py#L32 could be modified as:

json_fpath = Path(json_fpath)
json_fpath.parent.mkdir(parents=True, exist_ok=True)
with json_fpath.open("w") as f:
    json.dump(dictionary, f)
