DataBlock from Tensor of images

Part 1 (2019)
1

Hi,

I re-programmed the notebook for chapter4, MNIST.
Reflecting on it I like to alternatively create a DataBlock from the list of three and seven tensors and subsequently try different models.
However so far I failed creating a DataBlock, where get_items = list_of_tensors.
Does anybody have an example that explains how to do that?

thanks
Norbert
