NameError: name 'trimesh' is not defined

I came across this message many times and tried pip install trimesh then put import trimesh in rasterizer_context.py but it didn't work. I was quite upset.

I had the same issue on my Mac M3 and it was related to this issue: #26

Genesis doesn't use trimesh from pip install, but from genesis/ext/trimesh. See here. You can check by

from genesis.ext import pyrender, trimesh
from genesis.ext.pyrender.jit_render import JITRenderer

to figure out why it is not imported.

Thanks so much for your replies. The problem was solved when I perform the following steps referring to #26.

1. Pip install trimesh and pyrender
2. Turning the origin try-except to

try:
     from genesis.ext import pyrender, trimesh
     from genesis.ext.pyrender.jit_render import JITRenderer
except:
    import trimesh
    import pyrender

Then the error message turned into OpenGL error. To solve it, I use pip install -U PyOpenGL to upgrade it to the latest version and solve the problem. Also, reinstall genesis-world may also work.

@Yzhang367 Python needs to be built with Tk. I've provided some instructions here
