Py.mesh error, and viewer not appear. Urgent help

Why does py.mesh part appears an error?
also, it doesn’t seems to save any files.
I can’t see the viewer,too
I’m using zed with windows 11 and python 3.10
my SDKs are all new version.
It doesn’t do anything after printing
Extracting Point Cloud…

Filtering Mesh…

What’s the matter with it?
the other samples such as depth sensing and positional tracking works well with a viewer, without any problem.


It seems your variable is undefined. Can you share the full code and where you found it ?
