ImportError: cannot import name '_C'

[WangKun-KL]

After I installed the odi_env.yaml provided by you and ran it, the following error occurred:

Traceback (most recent call last): File "/tmp/pycharm_project_181/ODI-main/eval_attacks.py", line 14, in from attacks import * File "/tmp/pycharm_project_181/ODI-main/attacks.py", line 28, in from pytorch3d.io import load_objs_as_meshes, load_obj File "/tmp/pycharm_project_181/ODI-main/pytorch3d/io/init.py", line 8, in from .obj_io import load_obj, load_objs_as_meshes, save_obj File "/tmp/pycharm_project_181/ODI-main/pytorch3d/io/obj_io.py", line 22, in from pytorch3d.renderer import TexturesAtlas, TexturesUV File "/tmp/pycharm_project_181/ODI-main/pytorch3d/renderer/init.py", line 7, in from .blending import ( File "/tmp/pycharm_project_181/ODI-main/pytorch3d/renderer/blending.py", line 10, in from pytorch3d import _C ImportError: cannot import name '_C'

Do you know the reason for this?
