During constant folding process, TensorFlow checks if nodes that have constant input produces constant outputs and replaces them with constants. In our case, it can happen as DALI op provides a deterministic output when running once just after construction. Also, DALI op provides CPU variant so now TensorFlow can run DALI on CPU for constant folding examination. To prevent this DALI op needs to tell that it is stateful.
