Keras: ImportError: No module named data_utils

问题:

I am trying to import the module keras.utils.data_utils but 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.models and keras.layers.core?

ImportError: No module named data_utils

See here for the answer.

Even though this answer is correct but is not complete. Thanks to Ben J.'s answer but Tadhg McDonald-Jensen is the first one offering me the answers here.

Summarize it

I was using pip install keras to install keras, but it did not install the latest version of keras according 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 LSTM but not from keras.utils.data_utils import get_file. Because it is not in the previous versions.

SO, just clone the keras from their github, cd into it, and run sudo python setup.py install will solve this problem.

REMEMBER, if you already did this pip install keras, you have to make sure clear all keras versions you have installed by doing this pip uninstall keras many time until no keras existing, then do this sudo python setup.py install.

回答2:

I looked at the tar.gz from https://pypi.python.org/pypi/Keras/0.1.3 and there is no file named data_utils.py in the utils folder. However the github does include this file: https://github.com/fchollet/keras.

I hope your issue is resolved by now, if not:

sudo pip install git+git://github.com/fchollet/keras.git --upgrade

should do the job for you.

回答4:

this might solve your problem.

sudo -H  pip3 install git+https://github.com/fchollet/keras.git --upgrade
