No module named 'tensorflow.nn.dynamic_rnn'

This error message suggests that the module 'tensorflow.nn.dynamic_rnn' is missing and cannot be found by the interpreter. The dynamic_rnn module is used for building recurrent neural networks in TensorFlow.

One solution to this issue is to check if TensorFlow is installed correctly and if the specific version being used supports the dynamic_rnn module. If TensorFlow is installed correctly, but the dynamic_rnn module is still missing, you may need to update to a newer version of TensorFlow that includes this module.

Another possibility is that there is a typo in your code, and you have misspelled 'dynamic_rnn' or imported it incorrectly. You can double-check your code to make sure that you have correctly imported the module and spelled it correctly.

If you are still encountering issues, you can try searching online for similar issues and solutions or seek help from the TensorFlow community.
