My operating system is windows 10, when I replace the .obj path "test/unit_tests_data/bunny_oded.obj" with "./unit_tests_data/bunny_oded.obj", this error can be settled.

Change

from .context import gpytoolbox from .context import numpy as np from .context import unittest

to

import gpytoolbox import numpy as np import unittest

since there is no context file in the directory.

It seems OK, running the test code outputs

To uncomment igl.write_obj("output.obj",u,g), first import igl, and igl is installed using pip install libigl.

import igl # by pip install libigl igl.write_obj("output.obj",u,g)

How to show the triangle mesh, where the faces. vertices and edges can be colored as I need?

[sgsellan]

Hi!

I see you're trying to run our unit tests. I believe you may be running them in the wrong directory: you are supposed to run them from the home directory gpytoolbox as follows (i.e., not inside test/):

python -m unittest -v

Thanks, it's OK now.
