Hi, I get a butteraugli 0 score when processing this images. Butteraugli can be in a range between 1.0 and 1.5 (when quality is 95), but I think 0.0 is wrong. What's wrong?

butteraugli_main is the latest most updated version of butteraugli that you get when you compile Pik

Thank you for replying. I just tried your images, and I could get normal butteraugli values. Can you try these images at your convenience? images_1024.jpg is input image and guetzli_images_1024.jpg is output image after processing guetzli.
