i had the same problem. and my keras versions is 2.7.0 and my tensorflow version is 2.7.0 and yet the line

keras.utils.Sequence

didnt work for me. you can use

keras.utils.all_utils.Sequence

instead

Newer versions of keras==2.4.0 and tensorflow==2.3.0 would work as follows.

Replacing:

from keras.utils import np_utils

for

from keras import utils as np_utils

I getting same error in Keras 2.4.3. when writing

from keras import utils

or

from keras.utils import to_categorical

Solving:

from keras.utils import np_utils

Apparenytly this changes from version to version.

For Keras Version- 2.5.0 and TF Version- 2.5.0

from tensorflow.keras.utils import to_categorical

and work with

keras.utils.to_categorical()

Ran the above code by using keras==2.2.4 and tensorflow==1.14.0.

No errors.

Upgrading TensorFlow should solve the issue. Cheers :)

I'm running Tensorflow version 2.5.0. By trial and error, I found that keras.utils.np_utils works. I guess they moved it into np_utils in some update, so with that .to_categorical works just fine.

change "np_utils.to_categorical" by "keras.utils.np_utils.to_categorical"

I'm running Tensorflow version 2.6.0. on colab. By trial and error, I found that tf.keras.utils.to_categorical(y_train, num_classes) works.

The latest version of Keras for Tensorflow needed a change from:

tf.keras.Sequential()

to

keras.Sequential()
