Failed to find keypoints in .csv file generated (containing Keypoints) in run_render.py

[ronakgupta]

When I ran run_render.py, it generated synthetic images (218) and visible keypoints (.csv file). The number of visible keypoints vary from 1 to 12 (max).

But when I ran run_crop.py, its unable to find the keypoints and gave the following error:

Failed to find keypoints in crop /media/dell/STORAGE/data/syn_images/02924116/1582c81bf7dff678d26b2d2076566bb8/02924116_1582c81bf7dff678d26b2d2076566bb8_a014_e-04_t001_d001.png

The synthetic image with the above name and corresponding keypoints file (.csv) does exist in the syn_images folder.
