The errors all drop quickly but ... have you ever met this problem? I tried but failed to find where this error comes from.
It seems that some data are needed but missed. Maybe the labeled data?

I'm sure I followed all your descriptions and the human3.6m and 3dpw data has placed properly and input totally.
Could you please give me a little guidance? I'll be very appreciated it. Thank you!

it seems that image doesnt exists at imagepath. Set numwoker=0, and then check whether imagepath is correct by using ‘try except ‘
