maisi:

    "dummy6": 129,
    "dummy7": 130,
    "dummy8": 131,

vista3d in model zoo:

    "kidney mass": 129,
    "liver tumor": 130,
    "vertebrae L6": 131,

vista3d tutorial:

    "kidney mass (deprecated)": 129,
    "liver tumor (deprecated)": 130,
    "vertebrae L6 (deprecated)": 131,

Hi @Can-Zhao @heyufan1995 , could you help to confirm if we can use a single version to cover all maisi and vista3d tutorials and bundles? Which version should we use?

As we internally discussed before, it would be nice if we can have individual label JSON for each model. But the file should be visible publicly in MONAI tutorial repo and we should use commit hash in the link to ensure the right version to be called.

vista3d is updated in #657
