question about cano_weight_volume

[liwenssss]

I followed the process in gen_weight_volume.py to generate cano_weight_volume, and I referenced the code at

AnimatableGaussians/gen_data/gen_weight_volume.py

Line 179 in 7799264

# np.savetxt('../debug/pts_w_val.txt', smpl_model.lbs_weights.cpu().numpy(), fmt = '%.8f')

to compare pts_w_query with pts_w_val. I found that some values have discrepancies reaching the order of 0.1. Is this normal, and how significant is the impact on the final results?
Additionally, in your process, do you not optimize cano_weight_volume, but rather directly use the weight values from cano_weight_volume?

The error is acceptable because the solver cannot guarantee exactly the same LBS values of the sampled points. We do not optimize the LBS weight volume.
