` 在训练DenseNet 121, 下面的关于add_sublayer的代码训练时出现一个问题。请问要如何解决？

    self.feature0=Sequential()
    self.feature0.add_sublayer('conv1',
                      Conv3D(n_input_channels,
                            num_init_features,
                            filter_size=(conv1_t_size, 7, 7),
                            stride=(conv1_t_stride, 2, 2),
                            padding=(conv1_t_size // 2, 3, 3)))`
