from_numpy() method for tabular data

[sachinruk]

Hi all,

Just wondering if there was a from_numpy function similar to from_dataframe shown here. Ideally it would work something like from_numpy(x1, x2, target=y, batch_size=32). If not happy to make a PR if someone can point me in the right direction.

Thanks,
Sachin

Hi @sachinruk, we do now have a from_numpy for ImageClassificationData but not for tabular. A PR would be very welcome 😃 It could be added by creating a NumpyDataSource for tabular and adding it in the TabularPreprocess. Here's the ImageNumpyDataSource: https://github.com/PyTorchLightning/lightning-flash/blob/c28bafa4e7fb47d41b6a395ac8a83c6363d978a5/flash/image/data.py#L45

And here's where it's added in the ImageClassificationPreprocess: https://github.com/PyTorchLightning/lightning-flash/blob/c28bafa4e7fb47d41b6a395ac8a83c6363d978a5/flash/image/classification/data.py#L63

Hope that helps!
