Don't extract again automatically

[andyfelder16]

Hi, I use this model to train it with a lot images, those images will be updating constantly (like with a 1 week frequency). I have a cron that runs the model with the new images and generates the output files with the model trained with the new images.

The problem is that I have an API that uses the model and needs to use the latest files, but when it finds that already exists the files (when I run the run_index() function) it asks for a user input, I need that always reply to not extract them again (because the cron will already have updated the files).
