Description
I successfully installed nr3d_lib and ran neuralsim on Ubuntu 22.04, CUDA 12.1, python 3.10.15. Here are some problems I encountered and solutions for your reference.
Installing nr3d_lib:
Some subprocesses are preventing me from installing nr3d_lib on my machine.
Q1: A pybind11 error caused a subprocess installation error for nr3d_lib : "error: expected template-name before ‘<’ token"
Solution to Q1: I fixed this by editing /usr/include/pybind11/cast.h according the reference link https://github.com/pybind/pybind11/issues/4606.
Q2: After solving Q1, I encountered "Fatal error: glm/glm.hpp: No such file or directory"
Solution to Q2: I fixed this by running
sudo apt-get install libglm-dev
With the two issues fixed, I successfully installed nr3d_lib.
Running neuralsim:
When running nerualsim according to the official streetsurf guidelines, I ran into an issue with no frame_timestamps. Dataset I used the example of processed data provided by the official readme.
Solution: What I found to be causing this problem is that the processed data demo provided by the authors were obtained from an older version of the preprocess.py file. Therefore, if we want to run the latest neuralsim program, we need to repreprocess the original waymo data with a new preprocess.py file.
These questions are written by my painful memory during the installation process, any questions are welcome to leave a message to discuss.
