安装tcnn报错ld cannot find -lcuda No such file or directory

安装tcnn 报错

/home/soon/miniconda3/envs/nerfstudio/compiler_compat/ld: cannot find -lcuda: No such file or directory
......
ERROR: Failed building wheel for tinycudann

定位到是找不到动态链接库
首先查看是否有libcuda.so

ls /usr/lib/x86_64-linux-gnu/libcuda.so.1

然后在/usr/local/cuda/lib64中软连接这个动态链接库

ln -s /usr/lib/x86_64-linux-gnu/libcuda.so.1 /usr/local/cuda/lib64
ln -s /usr/lib/x86_64-linux-gnu/libcuda.so /usr/local/cuda/lib64

再次安装

pip install .

问题解决
