undefined symbol runing inspect_rendering.py

[nicetryzz]

I think this project is fantastic and works very well for 3D reconstruction in autonomous driving. However, I am currently trying to debug the ray tracing process, and I found that the inspect_rendering.py script fails to run. It produces the following error:
_sphere_trace.cpython-38-x86_64-linux-gnu.so: undefined symbol: _Z9ray_marchRK9DenseGridN2at6TensorES3_S3_S3_b
I don’t have much experience with C++ and CUDA. Could you please help me with this issue?
