I am using this github repo: <https://github.com/vchoutas/smplify-x> and I am running a script. I get the following error. How can I fix it? I understand I might have to convert `-` to `~` however not sure where it exactly is. I don't want to downgrade my PyTorch.

```
$ cat fit.sh
export CUDA_VISIBLE_DEVICES=0
python smplifyx/main.py --config cfg_files/fit_smplx.yaml --data_folder ../../data/smplify-x/DATA_FOLDER --output_folder ../../data/smplify-x/RESULTS --visualize="False" --model_folder ../../data/smplify-x/models_smplx_v1_1/models/smplx/SMPLX_NEUTRAL.npz --vposer_ckpt ../../data/smplify-x/vposer_v1_0 --part_segm_fn ../../data/smplify-x/smplx_parts_segm.pkl
