ImportError: cannot import name np_utils

I’m trying to run the following example from keras

but I get this error:

ImportError

ImportError: cannot import name np_utils

I’m using Ubuntu and I installed keras with:

sudo pip install keras

      np_utils is a separate package (and a keras dependency – which doesn’t get install with it). Can be installed using pip:

      pip install np_utils

      using – Keras==2.0.6

      Suggestion:
      For some odd (and still unknown) reasons, even after installing the import 

      from keras.utils.np_utils import to_categorical

      didn’t work – I had to restart the notebook (first restart even didn’t work), and once it worked, I got stuck again for same import call (gave exception for no module named tensorflow) – as in utils there’s another import from . import conv_utils, which required the tensorflow.

      I did try installing tensorflow using pip install tensorflow gave:

      Could not find a version that satisfies the requirement tensorflow
      (from versions: ) No matching distribution found for tensorflow

      even this gist didn’t work for me.

      Finally, I installed Anaconda – which have all the scientific packages (numpy, scipy, scikit-learn,..) pre-installed. Installed keras:

      conda install keras

      Best thing was, it even installed tensorflow as its dependency.
