### Steps to reproduce
```
import tvm
from tvm import relax
from tvm.script import ir as I
from tvm.script import tir as T
from tvm.script import relax as R
@I.ir_module
class Module:
@R.function
def main(v1_0: R.Tensor((1,), dtype="float16"), v6_0: R.Tensor((1, 40,
25, 1), dtype="float16")) -> R.Tensor((), dtype="float16"):
with R.dataflow():
lv: R.Tensor((), dtype="float16") = R.sum(v6_0, axis=None,
keepdims=False)
R.output(lv)
return lv
mod = Module
mod = tvm.relax.transform.DeadCodeElimination()(mod)
mod = mod.show()
mod = tvm.relax.transform.LegalizeOps()(mod)
```
