Hi！I have a question about the Shape of some Tensor type parameters in the spamGAN model.Why do Shape parameters in some models have "?"?And some parameters have two "?"For example, the parameter 'fake_seq: Tensor("disc_train/strided_slice_2:0", shape=(?,?), dtype=int32) ', I'm not sure what they mean,Can you help me out,thank you
