【问题描述】：
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。然而，在运行“text_classification_character_rnn.py”示例时，我遇到了一个错误：
Traceback (most recent call last):
File "/home/me/Projects/skflow/examples/text_classification_character_rnn.py", line 70, in <module>
classifier.fit(X_train, y_train)

_AssertCompatible(values, dtype)

(dtype.name, mismatch))
TypeError: Expected float32, got <tensorflow.python.framework.ops.Tensor object at 0x7f415dfcc290> instead.
关于我做错了什么有什么想法吗？此外，text_classification_cnn.py 正在工作，但print('Accuracy: {0:f}'.format(score)) 没有打印精度。我正在使用 PyCharm Edu 2.0.3 运行代码。
