TVM`s debug mode exclusive error

Troubleshooting
1

Hello everyone,

I was experimenting with TVM and wanted to use the Debug mode build to see if it would make understanding the C++ back-end easier. The problem is that after building TVM using the cmake debug flag echo "set(CMAKE_BUILD_TYPE Debug)" >> config.cmake the test.py script that I made to test some functionalities stopped working.

Here is the snipet of the code where the error occurs:

@tvm.script.ir_module
class Module:
    @R.function
    def main(
        A: R.Tensor((2048, 2688), "float32"),
        B: R.Tensor((2688, 2304), "float32")) -> R.Tensor((2048, 2304), "float32"):
        with R.dataflow():
            matmul: R.Tensor((2048,2304),dtype="float32") = R.matmul(A, B, out_dtype="void")
            R.output(matmul)
        return matmul

mod = relax.transform.LegalizeOps()(Module)

The error is in the operation mod = relax.transform.LegalizeOps()(Module).

Here is the error output:

tvm.error.InternalError: Check failed: (eq(a->condition, b->condition)) is false: When a TE compute node produces multiple outputs, each of which is a reduction, each reduction must be structurally identical, except for the ReduceNode::value_index.  However, the predicate T.bool(True) does not match T.bool(True)

The full error message is very long so I didn’t place it here (let me know if I should).

The thing is that this error doesn’t occur when using the RelWithDebInfo cmake mode, so i thing the problem is with the Debug mode.

Can someone help me out identifying the issue here?
