TX2 之 jetson-inference安装、分割模型推理测试记录

官方配置参考：https://github.com/dusty-nv/jetson-inference/blob/master/docs/building-repo-2.md

一、基于TX2的jetson-inference安装：

1.安装依赖

$sudo apt-get install git cmake

2.clone the jetson-inference repo

$ git clone https://github.com/dusty-nv/jetson-inference
$ cd jetson-inference
$ git submodule update --init

3.Configuring with CMake

1.注释掉CMakePreBuild.sh中下载模型、解压模型的带以下关键词的代码，不去下载那些模型文件
 
#sudo apt-get install -y libopencv-calib3d-dev libopencv-dev 
#wget
#mv
#tar -xzvf
 
 
2.cmake安装
$ mkdir build
$ cd build
$ cmake ../
 
##cmake 错误总结##
=========================================================================================
error 1.如果上面cmake出错如下提示(jetson nano开发板不会出现这个问题），则使用下面solve解决方案1的命令行进行cmake：
error1:cmake ../
CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find CUDA (missing: CUDA_CUDART_LIBRARY) (found suitable exact
  version "9.0")
Call Stack (most recent call first):
  /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)

  trt-console/CMakeLists.txt:4 (find_package)
 
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

-- Configuring incomplete, errors occurred!
See also "/home/nvidia/jetson-inference/build/CMakeFiles/CMakeOutput.log".
 
解决方案1（solve）：
$cmake -DCUDA_CUDART_LIBRARY=/usr/local/cuda/lib64/libcudart.so ../
========================================================================================
error 2.不能兼容opencv 4.0.0版本
解决方案2（solve）：
修改工程中jetson-inference/tools/trt-console/CMakeLists.txt
改为：find_package(OpenCV 4.0.0 COMPONENTS core calib3d REQUIRED)
========================================================================================
error 3.没有支持python3.5版本的接口
解决方案3（solve）：
3.1 修改工程中jetson-inference/python/CMakeLists.txt 第8行
改为：set(PYTHON_BINDING_VERSIONS 3.5 3.6 3.7)
 
3.2 修改工程中jetson-inference/utils/python/CMakeLists.txt 第8行
set(PYTHON_BINDING_VERSIONS 3.5 3.6 3.7)
========================================================================================

4.Compiling the Project

$ cd jetson-inference/build			# omit if pwd is already /build from above
$ make
$ sudo make install
