I add mvdream-sd21.yaml to gradio/mvdream-sd21.yaml. And I try to run on gradio. But I meet to problem.
File "/project/MVDream-threestudio/gradio_app.py", line 149, in
int(re.match(r"it(\d+)-0.png", os.path.basename(f)).group(1))
AttributeError: 'NoneType' object has no attribute 'group'

How to solve it?

I match the 0,1,2,3 tensors of mvdream-sd21 with re.match(r"it(\d+)-[0123].png).
But I meet another problem. How to show the 3D mesh in gradio web demo?
