Can't download mnist_784

[ricoderks]

Hi,

Thanks for the awesome tutorials!!

I was going through the neural network chapter (https://carpentries-incubator.github.io/machine-learning-novice-sklearn/07-neural-networks/index.html) and noticed that the fetch_openml() function was not working. It gives a download error.
I checked openml.org and can't reach that as well. Maybe it's something temporary, but I thought I let you know!

Error / warning:

/home/xxx/anaconda3/lib/python3.12/site-packages/sklearn/datasets/_openml.py:107: UserWarning: A network error occurred while downloading https://api.openml.org/api/v1/json/data/list/data_name/mnist_784/limit/2/data_version/1. Retrying...
  warn(

And after a long while it comes with this error:

URLError: <urlopen error [Errno 110] Connection timed out>

Cheers, Rico

Has this problem been resolved？

To be honest, I think the problem is at openml.org not here! Justed wanted to inform them.

OpenML is currently unreachable because of a cyberattack that hit TU Eindhoven. OpenML itself is not affected and we're in contact with the university IT team to bring it back soon.

In the meantime, we are preparing to set up a secondary server (on an entirely different network) in the Dutch supercomputing center so that such an outage won't happen again.
