Add `DataframeDataset` example

[wangjiawen2013]

Hi, The dataframe dataset has already been merged into burn and is demonstrated in burns book:

But I cannot find it in burn's docs and examples, where is it ?

Hello,

The code is separated in differents crates. You Can find the dataset crate under the crates folder: https://github.com/tracel-ai/burn/tree/main/crates%2Fburn-dataset.

You can find an example of the InMemDataset:

• InMemDataset: https://github.com/tracel-ai/burn/tree/main/examples/custom-csv-dataset

I don't know if there are more examples

Right now there are no examples which make use of the DataframeDataset (which is under the dataframe feature flag for the dataset module).

I agree that it would be nice to have at least a snippet for its usage. I'll convert this issue to track this addition.

Yeah it'd be great if we have example. Meanwhile you can see some basic tests:

BTW, the API is available via a dataframe feature flag.
