Environment information

• Operating System: Google Colab

• Python version: 3.10.12

• tensorflow-datasets version: 4.9.2

• tensorflow version: 2.12.0

• Does the issue still exists with the last tfds-nightly package (pip install --upgrade tfds-nightly) ? Yes.

Reproduction instructions

import tensorflow_datasets as tfds
iris, iris_info = tfds.load('iris')

Expected behavior Load iris dataset successfully.

It seems like same issue as citrus_leaves raises 404 Error.

Hi @arti1117 , thank you for reporting this issue!

commit #4957 32c00bb is now merged which fixes the url in the iris dataset. The change will be reflected in tfds-nightly in a couple of days max and in tensorflow-datasets in the next release.
