Hi @rayk , thank you for contacting us regarding the Sentiment140 dataset.

I was wondering why TFDS is trying to download https://www.cs.stanford.edu/people/alecmgo/trainingandtestdata.zip while the URL on the builder code is http://cs.stanford.edu/people/alecmgo/trainingandtestdata.zip (without www)?

Have you by any chance modified your local copy of the code?
