Hi @sgbihu - Thanks. This is a test that I added in #1816. Opset-11 Loop started supporting no variadic inputs. I added a Constant node in the Loop subgraph (which has no input) and the node's output is the Loop's output. I suspect that the Constant node gets constant folded at some point and the subgraph is left with no nodes. Is OpenVINO not able to handle this case? If so, can we just disable the test on OpenVINO citing unsupported scenario ? If there is some other isue, please let me know.
