when I run compute_coordinates.py, it shows the wrong result

[sunshinewhy]

Hi, why I always get [-1, -1] * 18 when I try to run compute_coordinates.py? Such as:
0000_c6s3_047142_03.jpg: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]
0609_c5s2_022005_05.jpg: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]
0304_c5s1_068698_01.jpg: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]
-1_c6s4_006527_05.jpg: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]: [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]
...
For any images I test, the cooridiantes always are [-1, -1] * 18, how can I solve this error?
Thanks a lot!

Did anybody solve this?

I also meet the same issue. Did you solve it?
