how to install mathutils?
when i install mathutils, i meet this error: /lib/python3.6/site-packages/mathutils-3.3.0-py3.6-linux-x86_64.egg/mathutils.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PyModule_AddType

Would appreciate it if you could reply!

Don't worry about this part. I think pytorch3d has provided relevant Lie-algebra operations which can be found here: axis_angle_to_matrix, matrix_to_quaternion. Reimplement relevant code snippets can avoid the dependences on mathutils.
