Keras: ImportError: No module named data_utils
提问by fluency03
I am trying to import the module keras.utils.data_utilsbut its not working. However, I can find this module here. It is indeed existing. Why I cannot import it while I can import some other modules likekeras.modelsand keras.layers.core?
我正在尝试导入模块keras.utils.data_utils但它不起作用。但是，我可以在这里找到这个模块。它确实存在。为什么我不能导入它而我可以导入其他一些模块，比如keras.models和keras.layers.core？

Even though thisanswer is correct but is not complete. Thanks to Ben J.'s answer but Tadhg McDonald-Jensenis the first one offering me the answers here.
即使这个答案是正确的，但并不完整。感谢Ben J.的回答，但Tadhg McDonald-Jensen是第一个在这里为我提供答案的人。
Summarize it
总结一下
I was using pip install kerasto install keras, but it did not install the latest version of kerasaccording to this. That is why I could do things like from keras.models import Sequential, from keras.layers.core import Dense, Activation, Dropout, and from keras.layers.recurrent import LSTMbut not from keras.utils.data_utils import get_file. Because it is not in the previous versions.
我是用的pip install keras来安装的keras，但是没有keras按照这个安装最新的版本。这就是为什么我会做这样的事情from keras.models import Sequential，from keras.layers.core import Dense, Activation, Dropout和from keras.layers.recurrent import LSTM而不是from keras.utils.data_utils import get_file。因为它不是在以前的版本中。
SO, just clonethe kerasfrom their github, cdinto it, and run sudo python setup.py installwill solve this problem.
所以，只要clone在keras他们的github上，cd到它，并运行sudo python setup.py install将解决这个问题。
REMEMBER, if you already did this pip install keras, you have to make sure clear all kerasversions you have installed by doing this pip uninstall kerasmany time until no kerasexisting, then do this sudo python setup.py install.
请记住，如果您已经这样做了，则必须通过多次执行此操作pip install keras来确保清除keras已安装的所有版本，pip uninstall keras直到不keras存在为止，然后执行此操作sudo python setup.py install。

I looked at the tar.gz from https://pypi.python.org/pypi/Keras/0.1.3and there is no file named data_utils.py in the utils folder. However the github does include this file: https://github.com/fchollet/keras.
我从https://pypi.python.org/pypi/Keras/0.1.3查看了 tar.gz ，在 utils 文件夹中没有名为 data_utils.py 的文件。但是 github 确实包含此文件：https://github.com/fchollet/keras。

I hope your issue is resolved by now, if not:
我希望你的问题现在已经解决，如果没有：
sudo pip install git+git://github.com/fchollet/keras.git --upgrade
should do the job for you.
应该为你做这项工作。
