Short description
Unable to load the LFW dataset via TensorFlow Datasets for about a month. The download fails with a NameResolutionError for vis-www.cs.umass.edu.
Environment information
Colab
Reproduction instructions
import tensorflow_datasets as tfds
ds = tfds.load("lfw", split="train")
Full stack trace:
WARNING:urllib3.connectionpool:Retrying (Retry(total=9, connect=None, read=None, redirect=None, status=None)) after connection broken by
'NameResolutionError("<urllib3.connection.HTTPConnection object at 0x7e382ee39cd0>: Failed to resolve 'vis-www.cs.umass.edu' ([Errno -2] Name or service not known)")': /lfw/lfw.tgz
Additional context
It appears the domain vis-www.cs.umass.edu is no longer resolving. Is there an alternate download URL or a recommended workaround so that tfds recognizes the dataset?

Hi @antoninasereb
I’d like to work on this issue. I’ll try reproducing it and investigate the cause.
