   This PR broke the layout_transform template used in graph tuner.
   https://github.com/apache/tvm/blob/54c995dbf7c96c1184c2baf64de87bc9566fe33a/python/tvm/autotvm/graph_tuner/base_graph_tuner.py#L54-L62
   
   I want to revert this PR. By design, the search space should have at least a length of 1. A template without any tunable knob is also valid and contains a valid schedule. The behavior of `np.prod` is what we want.
