标签： tensorflow rnn tensor cudnn

描述问题

tf.unstack未能按预期工作。它没有将R等级张量降低到R-1等级张量

源代码/日志

代码：

#! /usr/bin/env python
# -*- coding: utf-8 -*-

import sys
import tensorflow as tf
rnn_model = tf.contrib.cudnn_rnn.CudnnGRU(
        num_layers=1,
        num_units=64,
        direction='unidirectional')
rnn_model.build([3, 1, 3])
inputs=[[[1,1,1],[1,1,1],[1,1,1]]]
inputs_tensor= tf.convert_to_tensor(inputs, dtype=tf.float32)
print(tf.shape(inputs_tensor))
rnn_out, rnn_state = rnn_model(inputs_tensor)
print("rnn_state: ", rnn_state)
rnn_layers = tf.unstack(rnn_state)
print("rnn_layers", rnn_layers)

将代码粘贴到文件demo.py，然后从linux命令行运行：

$ python3.6 demo.py

输出：

Tensor("Shape:0", shape=(3,), dtype=int32)
rnn_state:  (<tf.Tensor 'cudnn_gru/CudnnRNN:1' shape=(1, ?, 64) dtype=float32>,)
rnn_layers [<tf.Tensor 'unstack:0' shape=(1, ?, 64) dtype=float32>]

rnn_layers应该是rnn_layers [<tf.Tensor 'unstack:0' shape=(?, 64) dtype=float32>]
