python - ImportError: cannot import name np_utils

Question

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 

This question was already asked but there was no answer: Keras: Cannot Import Name np_utils

Answer 1

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.
