Hey there! I’ve dealt with this exact import snag before, so let me walk you through the fix.

If you’re hitting an error when trying to import to_categorical with this line:

from keras.utils import to_categorical

It’s because in most recent Keras versions, this function isn’t located directly under keras.utils anymore—it lives in the np_utils submodule instead.

The correct import statement you need to use is:

from keras.utils.np_utils import to_categorical

Just swap out your original import with this one, and you’ll be able to use to_categorical to convert class vectors into binary class matrices without any hiccups.

Hope that gets you back on track quickly!
