Incorrect/outdated link in Beginner Quickstart guide.
Hi @sunny0531,

I have verified the reported problem and agree that the mnist link now asking for credentials to join. Will look into it and take appropriate action. Thanks! Hi @sunny0531,
I believe we need to use this link https://web.archive.org/web/20220331130319/https://yann.lecun.com/exdb/mnist/ instead of that link which requires credentials. I have verified the issue from my end. Thanks for the link! @Antonyj12 
And it seems to work on my device, so that might be a suitable replacement
Edit: Or you can use the mirror that tensorflow download the file  
2nd Edit: What if the server just down for a while? According to https://web.archive.org/web/20231031180229/https://yann.lecun.com/exdb/mnist/, the link still work at 31 Oct 2023. Should we just wait and see if it resolve itself? Hi @sunny0531 ,

The hyperlink to mnist dataset is removed with the above PR because it is external dependency and it won't affect the guide anyways. This issue is stale because it has been open for 7 days with no activity. It will be closed if no further activity occurs. Thank you. Seeing how the pull request is merged, I will close this now. Thanks for your help, especially @SuryanarayanaY Are you satisfied with the resolution of your issue?

It has a link to the MNIST dataset and it leads to http://yann.lecun.com/exdb/mnist/
I assume that used to be the right link but now it require login to visit? So should it be removed or is there a new website? 
Thanks!
