如何在V2中查看layer的output shape？
Created by: jianxiangm
比如在deepspeech2中，想查看某一层的输出shape，要怎么做呢？谢谢。 conv_layer = paddle.layer.img_conv( input=input, filter_size=filter_size, num_channels=num_channels_in, num_filters=num_channels_out, stride=stride, padding=padding, act=paddle.activation.Linear(), bias_attr=False)
