Error in Conversion of GRAB data from SMPL-X to SMPL+H

[shani1610]

Hi, While trying to run the conversion code i get the following error: AttributeError: 'Struct' object has no attribute 'hands_componentsl' Can you help me to solve it please?

more details: I am using smplx 0.1.28 , omegaconf 2.3.0 I put the correspondences exactly the way you mention in transfer_data directory. I'm running the main code from /object-popup/popup/utils/smplx2smplh in this way:

python -m main -g ./../../../data/preprocessed/grab_smplh/ -s ./../../../data/body_models/smplx/models

the folder structures are as follow:

grab_smplh
├── grab
│   ├── s1
│   │   ├── airplane_fly_1.npz
│   │   ├── ...
│   ├── ...
│   ├── s10
├── tools
│   ├── object_meshes
│   │   ├── contact_meshes
│   │   │   ├── airplane.ply
│   │   │   ├── ...
│   ├── subject_meshes
│   ├── ...

for the models:

models
├── smpl
│   ├── SMPL_FEMALE.pkl
│   └── SMPL_MALE.pkl
│   └── SMPL_NEUTRAL.pkl
├── smplh
│   ├── SMPLH_FEMALE.pkl
│   └── SMPLH_MALE.pkl
├── mano
|   ├── MANO_RIGHT.pkl
|   └── MANO_LEFT.pkl
└── smplx
    ├── SMPLX_FEMALE.npz
    ├── SMPLX_FEMALE.pkl
    ├── SMPLX_MALE.npz
    ├── SMPLX_MALE.pkl
    ├── SMPLX_NEUTRAL.npz
    └── SMPLX_NEUTRAL.pkl

Thank you!

Hi, this problem is likely caused by SMPL model files (there are a couple of similar issues in the SMPL-X repository). Make sure that you've downloaded the models from the corresponding pages, using the original SMPL+H model (not the extended AMASS version), and downloaded the file with correspondences smplx2smplh_deftrafo_setup.pkl.

I had the same issue, but after I followed this instruction https://github.com/vchoutas/smplx/blob/main/tools/README.md it was resolved. I recommend you to do this
