I converted the fbx to obj, then used the ParaView software to convert obj to vtp file, then used VMTK like above, but no matter which fbx I chose, the above error always occured . Why is that?

There is a non-ASCII character in one of the paths or file contents. As I see, the issue is that instead of simple quote (`"`) character you use some special character in your command.

Oh, thanks, indeed. The path has non-AscII characters.
