x = sequence.pad_sequences(x, maxlen=200)
from keras import utils as np_utils
y =np_utils.to_categorical(y, num_classes= 24)

I am using keras version 2.5 and tenser flow version 2.5 I import utils from keras

Answer 1

Newer versions of keras==2.4.0 and tensorflow==2.3.0 would work as follows so use:

from keras.utils import np_utils

and then replace keras.utils.to_categorical with

keras.utils.np_utils.to_categorical

Answer 2

U can also use from tensorflow.keras.utils import to_categorical this error pops up for a lot of attributes. Sometimes, clearly importing the attribute also helps, but in this case; you have to specify tensorflow.keras
