FileNotFoundError: [Errno 2] No such file or directory: './data/thumbsup30/cameras_sphere.npz'

Dear authors,
Thank you for the great work. I have a question about the dataset training.
When I run this command

# Train Tensor4D with image guidance on thumbsup_v4
python exp_runner.py --case thumbsup30 --mode train --conf confs/t4d_thumbsup_img.conf --gpu 0

It throws an error “FileNotFoundError: [Errno 2] No such file or directory: './data/thumbsup30/cameras_sphere.npz'” but I don't know where to find this dataset.
