So i have been working on a notebook on Google Colab, and all of a sudden i get the following error.
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-bd6ec74ccf2e> in <module>()
----> 1 from keras.utils import to_categorical
ImportError: cannot import name 'to_categorical' from 'keras.utils' (/usr/local/lib/python3.7/dist-packages/keras/utils/__init__.py)
---------------------------------------------------------------------------
NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

It's very strange since it was working just fine, and when i restarted my session, this happened. I tried with another google account too (in case there might be something wrong with my account's setup), but i still got the same error.
This is what i use to import the function.
from keras.utils import to_categorical
I'm wondering if anything change, and if anyone else experiences the same issue. Thanks.
from TF 2.0, it's been moved with tensorflow. please use this way:
from tensorflow.keras.utils import to_categorical
to_categorical([0, 1, 2, 3], num_classes=4)
result will be like
array([[1., 0., 0., 0.],
[0., 1., 0., 0.],
[0., 0., 1., 0.],
[0., 0., 0., 1.]], dtype=float32)
