TypeError: sequence item 0: expected str instance, int found

how to solve the question?

Hi, I didn't encounter this error before. But it seems that it failed to load open3d. In 'match_torch_ver = '.'.join( o3d torch version.release[:2] + ('*',))', o3d_torch_version.release[:2] is an integer, which should be a string. You may want to change the type of it by str()? This is an open3D error thus please also check if open3d was installed correctly:)

[caimingqi]

can you tell me the required open3d version

[mmmmimic]

I am using open3d 0.15.2

[caimingqi]

Is this the "processing 63.65％ points in region 2" when running? It is so slow.

[mmmmimic]

Yes, I am afraid it is slow.

I also encountered problems raised by others during the Scene segmentation，many values remain unchanged，Does it change to change the default super parameter，i may try it

Hi, I am sorry for the problem. As you may notice from the other post I failed to reproduce the error when I ran the experiments from scratch and I have no idea about this.

Hi, if you are still interested please check issue #7
