• 标题：简洁、精准概括您的问题
• 版本、环境信息：    1）PaddlePaddle版本：paddle 2.0    2）CPU/GPU：cpu    3）系统环境：Mac OS 10.14    4）Python版本号    5）显存信息 注：您可以通过执行summary_env.py获取以上信息。
• 复现信息：如为报错，请给出复现环境、复现步骤
• 问题描述：请详细描述您的问题，同步贴出报错信息、日志/代码关键片段 代码，我就添加了一个summary代码，想看看模型的结构，源代码地址为：https://github.com/PaddlePaddle/PaddleRec/blob/release/2.1.0/models/multitask/esmm/dygraph_model.py ：

  esmm_model = net.ESMMLayer(sparse_feature_number, sparse_feature_dim,
                                 num_field, ctr_fc_sizes, cvr_fc_sizes)
      inputs=[(2,3) for i in range(23)]
      info=paddle.summary(esmm_model,input_size=inputs,dtypes=int)
      print(info)

您好，paddle.summary目前不支持输入是个list的参数。https://github.com/PaddlePaddle/PaddleRec/blob/release/2.1.0/models/multitask/esmm/net.py#L79 我理解inputs是个list，装着多个shape一致的tensor。可以尝试把inputs中所有tensor concat起来，使得inputs是个tensor。
