这个错误是由于在使用 Keras 进行模型训练时,两个张量的形状无法进行广播运算所导致的。具体来说,在您的代码中,您使用了 Keras 的 Merge 层中的 Add 层,将两个张量进行相加。但是,这两个张量的形状不匹配,无法进行广播运算,所以会导致这个错误。
您需要检查一下您的代码,确定这两个张量的形状是否正确,并且可以进行相加操作。如果您没有修改过这个代码,可能是数据集的问题,您需要检查一下数据集的形状是否正确。

根据你提供的信息,这个错误是在使用 Keras 框架中进行训练时出现的。错误提示中指出了问题的源头是在 Bidirectional 层的第一个输入,它期望一个三维张量作为输入,但实际上输入的是一个四维张量。这可能是因为你的输入数据的维度不正确导致的。
你可以检查一下你的输入数据的维度是否正确。确保你的输入数据的维度是 (batch_size, time_steps, features),其中 batch_size 表示每个 batch 中的样本数,time_steps 表示序列的时间步数,features 表示每个时间步中的特征数。如果你的输入数据维度正确,你可以尝试将它们转换为正确的维度,例如使用 reshape() 函数,以便它们可以被正确地输入到模型中进行训练。

这个错误是由于 Keras 版本的问题导致的。在旧版本的 Keras 中,LSTM 层的参数是 return_sequences 和 return_state,而在新版本的 Keras 中,LSTM 层的参数是 return_sequences、return_state 和 return_attention。你可以检查一下你使用的 Keras 版本是否与代码中使用的版本相同。如果不同,你需要修改代码以适应你的 Keras 版本。另外,你可以尝试在 LSTM 层中添加 `return_sequences=True` 参数来解决这个问题。
