As of jax 0.4.27, arguments to jax.debug.callback are now jax.Array rather than np.ndarray (see https://jax.readthedocs.io/en/latest/changelog.html#jax-0-4-27-may-7-2024).

This break the tqdm updates with error TypeError: unsupported type for timedelta seconds component: jaxlib.xla_extension.ArrayImpl.

It looks like the fix would be to use jax.tree.map(np.asarray, args) on the callback args.
