Progress bar crash when empty dataset

[stridge-cruxml]

I accidentally filtered out all examples and tried to evaluate on an empty dataset.
Was getting a confusing crash in the progress bar code as self.target == 0.

Could you please share an example to reproduce the reported behavior. Thanks

So self.target was set to 0 in keras/src/utils/progbar.py, as i passed in a dataset with all examples filtered out 😮‍💨.

numdigits = int(math.log10(self.target)) + 1 then tries to take log of 0.
