max(): Expected reduction dim to be specified for input.numel() == 0

[zapan-669]

I get this error when trying to execute the Texture pipeline.

Is it a limitation of my gpu RTX 3090, and would it be better with a 5090 ?

assets_path    = /path/to/Hunyuan3D-2.1-main/assets'
image_path     = assets_path+"/demo.png"
obj_path        = assets_path+'/test.obj'
obj_path_tex    = assets_path+'/test_tex.obj'

paint_pipeline  = Hunyuan3DPaintPipeline( conf )
mesh_textured   = paint_pipeline( mesh_path=obj_path, image_path=image_path, output_mesh_path=obj_path_tex, save_glb=False,)

I encountered a texture generation error while developing the Windows-portable version. I believe the issue is due to insufficient GPU memory.
To address this, I made some modifications to the original gradio_app.py file from Tencent Hunyuan 2.1, which is likely the cause of the error you mentioned above.

Based on experience, the RTX 5090 should have sufficient memory to support texture generation.
Therefore, I recommend trying to replace your gradio_app.py with the official version from Tencent Hunyuan 2.1 and see if that resolves the issue.
