Missing output files when preprocessing on my own data

[TiantianWang]

Hi,

When I run the gen_run.py to preprocess my own data. For the step 10, errors are shown below when running optimize_smpl.py file.

########### can not find keypoints for 00000.png
can not find densepose for 00000.png
can not find keypoints for 00001.png
can not find densepose for 00001.png
can not find keypoints for 00002.png
can not find densepose for 00002.png ......
############

It seems that the Step 5 DensePose and Step 6 2D keypoints did not generate the required .npy file. May I know how to obtain both files for Step 5 and Step 6?

Thanks!
