Installation problem

Hello! When I install
It reported ./ 第343行 [:: 需要整数表达式

cp : 目标/usr/local/cuda/lib64不是目录。

and When I installed it ,I refuse to install cuda.

ubuntu20.04 without cuda .

@davidwang ZED_SDK definitely needs Cuda to run as per my understanding. You can reinstall SDK and choose to install Cuda or you can install Cuda separately by following these steps.

Thank you ,I solved it ,
I apt-get install some files. @Flash
