No defs regarding grid/block info in autoscheduler transform steps?

Hi there, I am trying to re-config tuned schedule saved in json.

({“i”: [["[“60cba4eb8adfa2537a0cb66713496aa8”, 16, 1, 28, 28, 32, 1, 3, 3, 1, 32, 1, 1, 16, 32, 26, 26]", “cuda -keys=cuda,gpu -max_num_threads=1024 -thread_warp_size=32”, [-1, 16, 64, 2147483647, 2147483647, 1024, 8, 32], “”, 0, []], [[], [[“SP”, 3, 0, 16, [2, 2, 1, 1], 1],[“PR”, 5, 0, “auto_unroll_max_step$16”]]]], “r”: [[6.68081e-06], 0, 1.20999, 1660380076], “v”: “v0.6”})

Although I read Explanation of autoscheduler transform steps, I am still wondering why there are no tuned grid/block info in the schedule? and where can I find the whole list of the search space during auto-tuning.
