ImportError when using mesh_extract_tetrahedra.py

[LucioSunj]

Hi when I use mesh_extract_tetrahedra.py, I encountered the ImportError that:

mesh_extract_tetrahedra.py", line 14, in <module>
    from tetranerf.utils.extension import cpp
  File "/home/qizhong/miniconda3/envs/radegs/lib/python3.9/site-packages/tetranerf/utils/extension/__init__.py", line 1, in <module>
    from . import tetranerf_cpp_extension as cpp
ImportError: cannot import name 'tetranerf_cpp_extension' from partially initialized module 'tetranerf.utils.extension' (most likely due to a circular import) (/home/qizhong/miniconda3/envs/radegs/lib/python3.9/site-packages/tetranerf/utils/extension/__init__.py)

Could you please help me with that?

I also faced the same issue.

I deleted all the newly generated files in submodules/tetra-triangulation, reinstalled tera-nerf, and it ran.

cd submodules/tetra-triangulation
conda install cmake
conda install conda-forge::gmp
conda install conda-forge::cgal
cmake .
# you can specify your own cuda path
# export CPATH=/usr/local/cuda-11.3/targets/x86_64-linux/include:$CPATH
make
pip install -e .

The reason why I reported an error here may be because I moved the location of RaDe-GS after I just started cmake. As a result, there may be problems with the contents of CMakeCache.txt.
