Feature-Rich Recommender Systems

https://d2l.ai/chapter_recommender-systems/ctr.html

Hi, the code references d2l.DATA_URL – where is this defined?

Also, do none of the later chapters work in PyTorch or TensorFlow? I can’t find those notebooks…

the url shall be http://d2l-data.s3-accelerate.amazonaws.com

Well, I can see there are links to COLAB(PyTorch) in the upper right corner of each tutorial but none of them seem to work, at least for the recommender systems chapter… It seems like a file error. Could anyone fix this problem?
