skflow example throws errors

I'm quite new to python and skflow, but I am experiencing a really basic problem and hope someone could help me.

I've installed skflow and downloaded the dbpedia_csv which is used in the examples. However upon running the 'text_classification_character_rnn.py' example, I am hit with an error:

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)

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

Any ideas on what I am doing wrong? Also, the text_classification_cnn.py is working, but the print('Accuracy: {0:f}'.format(score)) no accuracy is printed. I'm using PyCharm Edu 2.0.3 to run the code.

This looks like a version mismatch between skflow and TensorFlow. From the error message, it looks like you have an old version (0.5 or 0.6) of TensorFlow. However, skflow was recently updated to use a new interface in TensorFlow, and it looks like you are using this latest version of skflow.

The simplest solution would be to upgrade TensorFlow to version 0.7.1
