How to use "bool" in tvm.compute?

Questions

I tried like this:

import tvm

def great(shape, dtype):

    data1 = tvm.placeholder(shape, name="data1", dtype=dtype)
    data2 = tvm.placeholder(shape, name="data2", dtype=dtype)

    out = tvm.compute(shape, lambda *indice: tvm.select(data1(*indice) > data2(*indice), True, False), name = "out")

    s = tvm.create_schedule(out.op)

    print(tvm.lower(s, [data1, data2, out], simple_mode = True))
    

great((3,128), "float16")

There was an error:

Traceback (most recent call last):
  File "test_greater.py", line 23, in <module>
    great((3,128), "float16")
  File "test_greater.py", line 19, in great
    mod = tvm.build(s, [data1, data2, out], "cce", name = "great_cce")

tvm._ffi.base.TVMError: [14:43:59] include/tvm/./expr.h:68: Check failed: data_bits % 8 == 0U (1 vs. 0) Need to load/store by multiple of bytes

I found that the length of “bool” is 1, so how can i fix this?

in tvm\HalideIR\src\base\Type.h

/** Construct a boolean type */
inline Type Bool(int lanes = 1) {
    return UInt(1, lanes);
}
