I tried and it works on my computer. I think the problem might not be specific to these datasets. Could you please try with a different one? I notice that the dataset is not downloaded in the .julia/datadeps folder, but in the ./julia/scratchspaces folder.

[CarloLucibello]

Weird. I'm on julia v1.10.4. I tried to install just MLDatasets in a temporary environment and it still doesn't work. MNIST works instead.

[aurorarossi]

I tried it on 3 different machines (with Linux) also using the temporary env and it works. Are you working on Mac?

[CarloLucibello]

yes. Now I removed all the scratchspaces and then it worked. Maybe I previously had an interrupted download.

[CarloLucibello]

If a file is not found we should retry the download instead of erroring.
