tf.contrib.rnn.DropoutWrapper 

Defined in tensorflow/python/ops/rnn_cell_impl.py.

def __init__(self, cell, input_keep_prob=1.0, output_keep_prob=1.0,               state_keep_prob=1.0, variational_recurrent=False,               input_size=None, dtype=None, seed=None):Args:      cell: an RNNCell, a projection to output_size is added to it.      input_keep_prob: unit Tensor or float between 0 and 1, input keep        probability; if it is constant and 1, no input dropout will be added.      output_keep_prob: unit Tensor or float between 0 and 1, output keep        probability; if it is constant and 1, no output dropout will be added.      state_keep_prob: unit Tensor or float between 0 and 1, output keep        probability; if it is constant and 1, no output dropout will be added.        State dropout is performed on the *output* states of the cell.      variational_recurrent: Python bool.  If `True`, then the same        dropout pattern is applied across all time steps per run call.        If this parameter is set, `input_size` **must** be provided.      input_size: (optional) (possibly nested tuple of) `TensorShape` objects        containing the depth(s) of the input tensors expected to be passed in to        the `DropoutWrapper`.  Required and used **iff**         `variational_recurrent = True` and `input_keep_prob < 1`.      dtype: (optional) The `dtype` of the input, state, and output tensors.        Required and used **iff** `variational_recurrent = True`.      seed: (optional) integer, the randomness seed.
