tensorflow.contrib

在TensorFlow的v2版本中，已经舍弃了tensorflow.contrib模块。因此，在引用tensorflow.contrib时会出现ModuleNotFoundError的错误。[1][2]在v2版本中，相关功能可以通过安装tf_slim来引用。[1]此外，在v2版本中，tensorflow.contrib的功能已经被集成到其他模块中。[3]如果你想在v2版本中使用tensorflow.contrib的功能，你可以使用tensorflow.compat.v1模块来兼容v1版本的代码。[3]

tensorflow.contrib.rnn

The `tensorflow.contrib.rnn` module contains implementations of various recurrent neural network (RNN) cells and functions that can be used for building RNNs in TensorFlow. Some of the commonly used classes in this module are:

1. `BasicRNNCell`: Implements a basic RNN cell with a single hidden layer.
2. `LSTMCell`: Implements a Long Short-Term Memory (LSTM) cell.
3. `GRUCell`: Implements a Gated Recurrent Unit (GRU) cell.
4. `MultiRNNCell`: Implements a multi-layer RNN cell by stacking multiple RNN cells together.
5. `static_rnn`: Builds an RNN from a sequence of inputs using a specified RNN cell.

These classes and functions can be used to build various types of RNNs, such as language models, sequence-to-sequence models, and time series models.

tensorflow.contrib.slim

tensorflow.contrib.slim是TensorFlow的一个高级API，它提供了一些方便的函数和工具，可以帮助用户更轻松地构建和训练深度神经网络。它包含了一些常用的卷积神经网络（CNN）和循环神经网络（RNN）的模型，如VGG、ResNet、Inception等，同时也提供了一些常用的优化器和损失函数。使用tensorflow.contrib.slim可以大大简化深度学习模型的构建和训练过程，提高开发效率。
