I think you are supposed to call `decompose_reduction `before `blockize`: ``` import tvm from tvm.script import ir as I from tvm.script import tir as T @I.ir_module class Module: @T.prim_func def main(): # with T.block("root"): A_sum = T.alloc_buffer((1,), "float32") A = T.alloc_buffer((1, 16), "float32") for nn, ff in T.grid(1, 16): with T.block("A"): v_nn, v_ff = T.axis.remap("SR", [nn, ff]) T.reads(A[v_nn, v_ff]) T.writes(A_sum[v_nn]) with T.init(): A_sum[v_nn] = T.float32(0) A_sum[v_nn] = A_sum[v_nn] + A[v_nn, v_ff] sch = tvm.tir.Schedule(Module) a = sch.get_block("A") loop_n, loop_f = sch.get_loops(a) sch.decompose_reduction("A", loop_n) sch.blockize(loop_f) init_block = sch.get_block("A_init") print(sch.mod) # <-- A_init exists ``` -- This is an automated message from the Apache Git Service.
