I made a little progress; but help is really appreciated as Im kinda confused  
The issue seems to be directly at autokeras/auto_model.py at 78223dfc63056414e32e202b158dbc981be48dc9 · keras-team/autokeras · GitHub 3 just when I pass the tf.Dataset - its simply empty. I have checked numerous times but can confirm I am not passing an empty Dataset. strange. but I will surely double check.
Again, if anyone can expedite this process for me - that would be really appreciated!
