By the way, I was concerned for backwards compatibility so I ran a quick check and this fix does not break backwards compatibility. Users with datasets that contain scalar valued tensors and which serialized as pickle can still deserialize correctly.

@enrico-stauss Any feedbacks, suggestions about LitData so far ?

[enrico-stauss]

I haven't had very advanced use-cases but from what I can tell LitData works smoothly most of the times and if something comes up, it is a quick fix.

Will keep using it for the resource efficiency alone, so you'll probably see me around :)

Hey @enrico-stauss. That's great. Would you be willing to post on social about LitData ? I am trying to promote it a bit this month.

[enrico-stauss]

I (intentionally) don't really have much of a social media presence, so I don't think I can help you here @tchaton.
