skflow示例抛出错误

Question

我对python和skflow很陌生，但我遇到了一个非常基本的问题，希望有人能帮助我。

我已经安装了skflow并下载了示例中使用的dbpedia_csv。但是一旦运行了“text_classification_character_rnn.py”例如，我打一个错误：

Traceback (most recent call last): 
File "/home/me/Projects/skflow/examples/text_classification_character_rnn.py", line 70, in <module>

(dtype.name, mismatch)) 
TypeError: Expected float32, got <tensorflow.python.framework.ops.Tensor object at 0x7f415dfcc290> instead. 

任何的想法是什么，我做错了什么？此外，text_classification_cnn.py正在工作，但print('Accuracy: {0:f}'.format(score))没有打印准确性。我使用PyCharm Edu 2.0.3来运行代码。

这看起来像是skflow和TensorFlow之间的版本不匹配。从错误信息看来，它看起来像是一个旧版本（0.5或0.6）的TensorFlow。然而，skflow是recently updated在TensorFlow中使用一个新的界面，它看起来像你正在使用这个最新版本的skflow。

最简单的解决方案是upgrade TensorFlow到0.7.1版本
