[TVM Discuss] [Development] [Relay][concatenate]Downcast from relay.RefType to relay.TensorType failed."


There are some differences.  I try to implement the gradient of relay.concatenate， but it seems that TVM don't know how to downcast Tuple type data. The error log shows that: " Downcast from relay.RefType to relay.TensorType failed."
