NaN loss value, stopping!

[man1989]

python smplifyx/main.py --config cfg_files/fit_smplx.yaml --data_folder ./data 
--output_folder ./output --visualize False --model_folder ../smplx/models 
--vposer_ckpt ./vposer --part_segm_fn smplx_parts_segm.pkl

After running this i am getting below error

Found Trained Model: ./vposer/snapshots/TR00_E096.pt
init_t:  tensor([[0., 0., nan]], device='cuda:0')

Any help on this as why i am getting this error?

Update:-
After disabling interactive mode and disabling cuda and interpenetration Mesh got generated but it has NaN co-ordinates

How was your setup problem? I'm having same issue, any detail solutions?

I had the same problem and turned out the NaN values came from the output from the decoder of VPoser. The issue was with the version of VPoser (as mentioned here: #144 (comment)). You can try to install VPoser v1.0 from branch cvpr19 (pip install -e git+https://github.com/nghorbani/human_body_prior@cvpr19#egg=human_body_prior) and it should work.
