Using Kimodo-SMPLX Model

Using the Kimodo-SMPLX-RP-v1 model requires a few extra installation steps.

Request Model Access

The SMPL-X version of Kimodo is gated, so before trying to generate motions with it in the CLI or demo, go to the Hugging Face model page and request access. As described in the installation process, make sure your HF token is properly set up so your access to the model can be authenticated.

Download SMPL-X Body Model

If you want to visualize generated SMPL-X motions in the demo, you will need to download the SMPL-X body model. Go to the SMPL-X webpage and then sign in or create an account and go to the "Download" page. Click "Download SMPL-X with removed head bun (NPZ)" and then copy the SMPLX_NEUTRAL.npz file to the Kimodo codebase to be at kimodo/kimodo/assets/skeletons/smplx22/SMPLX_NEUTRAL.npz.

Note that if you installed Kimodo as a package without downloading the codebase, you'll need to find where the assets directory is located by running:

python -c "from kimodo.assets import skeleton_asset_path; print(skeleton_asset_path('smplx22'))"
