Do you have tensorrt installed on your machine? NvInfer.h is in package libnvinfer-dev

user@user-SYS-7048GR:~$ dpkg -L libnvinfer-dev

@wang-xinyu

After I installed tensorrt, the same error still occurred

My version of tensorrt is 5.1.5.0

When I input dpkg - L libnvinfer dev

Indicates that libnvinfer dev is not installed

Thank you for your help

[wang-xinyu]

@wangtianlong1994 It's libnvinfer-dev.

我查找这个包后，显示我没有安装这个包，但是我是安装好TensorRT的，请问这种情况该怎么解决

[apple2333cream]

我也遇到这个问题了，在cmakelist文件中添加tensorRT的安装路径之后就不报错了

include_directories(/home/wzp/project/trt/TensorRT-7.0.0.11/include)
link_directories(/home/wzp/project/trt/TensorRT-7.0.0.11/lib)

include_directories(/home/wzp/project/trt/TensorRT-7.0.0.11/include)
link_directories(/home/wzp/project/trt/TensorRT-7.0.0.11/lib)

请问在哪个文件内，如何添加呢？
