About v_template in checkpoint

[dldaisy]

Hi,
I'm trying to recover a smplx model from the saved params output by ExPose and overlay it on the original image.
However, I noticed that there is a shift from the rendered image and the original people.
After checking the code, I find that this problem is caused by the 'v_template' field loaded from checkpoint. To be specific, the 'v_template' in SMPLX_NEUTRAL.pkl is a bit different from that in the checkpoint file. (name of v_template in checkpoint is smplx.body_model.v_template).
Thus, I want to ask about the reason why the difference exists. Thanks a lot!

I've been struggling to reproduce the rendered images and after debugging I've just found this too. My guess is that the checkpoint used an older version of SMPL-X and, after updating SMPL-X, the data attached to ExPose got outdated.

It would be good to have an explanation or a fix so the results can be fully reproducible. Sorry for the mention, @vchoutas, but can you provide info about this? Thanks.
