Hey, GLB can contain multiple geometries and a scene graph, so the return type is a trimesh.Scene to contain that information. If you run the pyrender scene conversion it should work:
pyrender.Scene.from_trimesh_scene(fuz_trimesh)
There are a few formats that can return a Scene OR a Trimesh (OBJ), it might be nice someday to have something like pyrender.utils.from_trimesh that could handle any input.

import trimesh
import pyrender
fuz_trimesh = trimesh.load("donut_calibrate2_forgltf.glb")
mesh = pyrender.Mesh.from_trimesh(fuz_trimesh)
In the line 3 if you want to force it to return a Mesh object, instead of a scene object try to use 'force' option of .load() method.
Example:
fuz_trimesh = trimesh.load("donut_calibrate2_forgltf.glb", force='mesh')
There are other force options inside this method. you can look into the documentation for detailed info.

Thanks and yes. Just tried again, it was able to convert scene. But then it's getting another error.
scene = pyrender.Scene()
scene.add(mesh)
Error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\Python36\lib\site-packages\pyrender\scene.py", line 286, in add
raise TypeError('Unrecognized object type')
TypeError: Unrecognized object type
Hmm, is it able to import armature?

I think you want:
scene = pyrender.Scene.from_trimesh_scene(fuz_trimesh)

￣□￣| | Thank you. Another question: I'm trying to visualize animation clip by pyrender.Viewer(scene, use_raymond_lighting=True, run_in_thread=True) Then got error:

You can create a list to load all elements in the trimesh.geometry.values() and add them into scene one by one
