关于create_embedding_dict里面embedding_name 重复的问题

Please refer to the [FAQ](https://deepmatch.readthedocs.io/en/latest/FAQ.html) in doc and search for the [related issues](https://github.com/shenweichen/DeepMatch/issues) before you ask the question. **Describe the question(问题描述)** 在 create_embedding_dict 函数中，使用特征的embedding_name 作为key来进行存储，那么如果特征的embedding_name 重复，事实上在例如在run_sdm里面用户序列中变长特征和item特征就是重复的。这样的话会导致得到的emd被覆盖，如果只需要一份embedding的话，那这样写还有什么意义？ ``` def create_embedding_dict(sparse_feature_columns, varlen_sparse_feature_columns,...

大数据场景下全量加载到显卡训练显然不现实，鄙人在TF2.4.0中试了下将数据处理好后分批给到DeepMatch模型，发现有以下问题： **1. 通过tf.data.Dataset.from_tensor_slices将数据分批后训练，却发现在tf.compat.v1.disable_eager_execution()后无法使用，报错如下：** D:\Anaconda3\envs\TF2GPU\lib\site-packages\tensorflow\python\keras\backend.py:434: UserWarning: `tf.keras.backend.set_learning_phase` is deprecated and will be removed after 2020-10-11.
