Checksums for the dataset imagenette has changed

[mr-ubik]

Does the issue still exist with the last tfds-nightly package (pip install --upgrade tfds-nightly)?

• Yes

Reproduction instructions

!rm -r ~/tensorflow_datasets/imagenette/
!rm -r ~/tensorflow_datasets/downloads
import tensorflow_datasets as tfds
tfds.load('imagenette')

@mr-ubik The imagenette dataset is successfully generated in tfds-nightly latest version. Please make sure you have installed this. (Also the expected checksums showed in your error logs are not the ones currently used in tfds-nightly) You might night to upgrade to the latest version. Thanks!

[mr-ubik]

@NikhilBartwal you are correct, I saw the issue persists even with tfds-nightly due to the dataset not being correctly removed in Colab.

@mr-ubik Does the issue persists even with the latest version of tfds-nightly(pip install --upgrade tfds-nightly)? If it does, please send full error logs along with tfds.__version__

@mr-ubik Please consider closing this issue if your query was answered. Thanks!
