cifar10.load_data() is not working

`(x_train,y_train),(x_test,y_test)=cifar10.load_data()
`
doesn't not work on colab, but this does:

```
import numpy as np
import tensorflow as tf
from keras.utils import to_categorical
from keras.datasets import cifar10
(x_train,y_train),(x_test,y_test)=tf.keras.datasets.cifar10.load_data()

```
