Problems with trimesh

[bugdary]

Does anyone encounter problems when trying to dump the scene?
I installed trimesh = 2.35.39 and I get the following problem :

Finished detection. 37 object detected.
Traceback (most recent call last):
File "demo.py", line 101, in
MODEL.dump_results(end_points, dump_dir, DC, True)

'geometry' in self.transforms.node[n]):
AttributeError: 'EnforcedForest' object has no attribute 'node'

Any ideas ?

I solved the issues by upgrading to the latest version of Trimesh and changing the following line:

trimesh.io.export.export_mesh(mesh_list, out_filename, file_type='ply')

to

mesh_list.export(out_filename)

Thanks for sharing your code.

I encountered the same error. After some digging, it looks like it is caused by the fact that the version of networkx installed is too new. For a method that does not involve changing the code: before installing trimesh, do pip install 'networkx>=2.2,<2.3'.

I have a similar problem. But the warning information is different. I don't know what to do. Can someone help me?

Is there any outstanding scholar who can help me. Thanks

@ai-starter have you tried pip install 'networkx>=2.2,<2.3' before installing trimesh? Your error message seems to be the same.

Thanks，It is useful! But I have another problem. When I open the results with meshleb, it looks weird. The result is some combination of cubes, which is different from what we see in the paper.
what happen? I look forward to your reply. Thanks

You need to change meshlab to only show the wireframes. Also, please open a new issue for this.
