Couldn't find a way to comment at the code location, so pasting the snippet below.
Should this be signatures instead? Seems to be running fine, so perhaps this variable is ignored.

       self.signitures = {
            'image_arrays': raw_images,
            'prediction': detections,
        }
        return self.signitures

See minor comment in conversation section.

However, the detection boxes look good/working, and seems like a good way to strip the DecodeBmp op, using batch_image_preprocess() (I assume). Approved!

signitures - good catch. But we need to spell it like this because the baseclass defines it like that and driver.export() is using it.
