Train Deep Learning Model erro

[forestfairy]

Hi,

I recently started working with ArcGis Pro and I'm trying to make some Deep Learning Model but keep having this error. I really don't know where it comes from, does anyone have a clue please ? I joined an image of the error message.

Thanks

the size of learn.data.train_dl was zero, meaning whatever it is supposed to be wasn't found.

Sorry, I can't flip back and forth to the image any more to narrow down if it was a path thing or something didn't work
