About the pose of hand

I got the pose of hands from the output of the demo code. When I apply the pose to an avatar, its hands have weird pose. I guess it is related to the parameter "flat_hand_mean" of the SMPLX model. So I am wondering if the Frankmocap is trained with flat_hand_mean=False? If I would like a initial "flat hand", should I train the model from scratch?

This sounds like the flat_hand_mean issue. You can quickly check it via setting flat_hand_mean to true/false.
To get initial flat hand, you just need to add or subtract the mean, no need to train the model from scratch.

Thanks for your quick reply! Could you please tell me how can I find the mean ? I did not find it in the original smplx code.

I believe you can find the mean in SMPL-X data. You may need to delve into their code to check how the mean is applied.
