Ran SRT3D using own .obj model and encountered the following error

I ran SRT3D using my own .obj model and encountered the following error:
**_**Could not open model file "/mnt/nvme2/datasets/RBOT_dataset_minor/ape/ape_model.bin"

After generating 7 views, the error "No valid contour in image" occurs. I am not sure what the cause is. My .obj model contains some holes, and I wonder if that might be the reason.
