【中文标题】ValueError：变量嵌入已经存在，不允许。您的意思是在 VarScope 中设置 reuse=True 吗？最初定义

【英文标题】：ValueError: Variable Embedding already exists, disallowed. Did you mean to set reuse=True in VarScope? Originally defined

【问题描述】：

基于此 github 链接 https://github.com/brightmart/text_classification/tree/master/a03_TextRNN 当我使用 google_news_wor22vec.bin 和 包含我的文档 + 标签的文本文件 运行 train a03_TextRNN 时，我有这些错误：

我该如何解决这个问题？

【参考方案1】：

这已经很晚了，但是我在寻找解决类似问题时发现了您的帖子。如果其他人在这里找到了方法，请在模型的开头添加此代码将解决问题：

tf.reset_default_graph()
