mesh_extract error!

[ywaison]

Thank you very much for the code you provided. When I was preparing to extract the mesh after training the model, I encountered an error as shown in the following figure. I am eager to get your help and hope to get your reply in time!

You should compile tetra-triangulation(cmake . and make) and pip install it.

Hi, I also meet this problem, how do you solve it?
