mixamo data processing

[Jiaqi-zhang]

Thank you for your excellent work. I read the mixamo_loader.py file and realized I needed to read the NPZ file. Can you provide the code for this part of the data processing?

        def _preload(self):
        for idx in self.names:
        c = np.load(os.path.join(self.data_dir, 'npz', idx+'.npz'))

        v = c["v"]
        center = (np.max(v, 0, keepdims=True) + np.min(v, 0, keepdims=True)) / 2
        scale = np.max(v[:, 1], 0) - np.min(v[:, 1], 0)
        v = (v - center) / scale
        joints = c["joints"]
        joints = (joints - center) / scale

        self.vs.append(v)
        self.fs.append(c["f"].astype(int))
        self.joints.append(joints)
        self.parents.append(c["parents"])
        self.joint_names.append(c["joint_names"].tolist())
        self.weights.append(csr_matrix((c["weights_data"], (c["weights_rows"], c["weights_cols"])),
                                       shape=c["weights_shape"], dtype=np.float32))
        self.tpl_edge_indexs.append(c["tpl_edge_index"].astype(int).T)
        self.geo_edge_indexs.append(np.stack([c["geo_rows"].astype(np.int32), c["geo_cols"].astype(np.int32)], 0))

Hi, I've updated the Mixamo processing part. Please check the latest readme.
