I noticed that, some dygraph demos in paddle2.0beta version just input nd.array class into the network. Does it have the difference between using to_variable() or to_tensor() to convert data and directly input ndarray ? If it does, what's the difference? Or which method should we use in paddle2.0beta. Thanks for your time and hope to get reply!
