The middle output relative depth map be midas are all 0?

When debugging sanity.py, it is found that the middle output relative depth maps by Midas are all 0. Why does this happen? Although the relative depth map is also used to recover the metric depth map in corporating with feature maps from the Midas network, the 0 relative depth map provides no information and is useless.
