Intel OpenVINO 安装显卡驱动

背景：

使用集合诚KMDA-3301 OpenVINO CPU和GPU 算法加速，用GPU加速时，调动不起来。写下解决过程，以备后用。

过程：

调动GPU 报错：

terminate called after throwing an instance of 'InferenceEngine::GeneralError'
  what():  Failed to create plugin /opt/intel/openvino_2021/deployment_tools/inference_engine/lib/intel64/libclDNNPlugin.so for device GPU
Please, check your environment
[CLDNN ERROR]. clGetPlatformIDs error -1001

先查 openvino环境配置
openvinotoolkit/openvino
得知没有显卡驱动：

$ cd /opt/intel/openvino_2021/install_dependencies/
$ sudo -E ./install_NEO_OCL_driver

使用原脚本下载时，所有 neo 目录下的文件可能下载不全，导致安装失败
这时修改下载方式

如果有原先的驱动，得先删除
参考OpenVINO安装之安装openCL

sudo apt purge intel-opencl

这时仍然不能调用GPU ，咨询Intel工程师得知内核得 5.8 以上，而原来内核是

$ uname -r
5.4.0-84-generic
$ uname -a
Linux t-Default-string 5.4.0-84-generic #94~18.04.1-Ubuntu SMP Thu Aug 26 23:17:46 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

这时有两种方法解决内核问题：

一. 升级内核

参考 在ubuntu18.04上更新内核
ubuntu18.04.4更换内核版本

1. 更新内核，更新到5.10 这时报错

make[1]: *** No rule to make target 'debian/canonical-certs.pem', needed by 'certs/x509_certificate_list'.  Stop.
Makefile:1837: recipe for target 'certs' failed
make: *** [certs] Error 2

参考：

内核错误: No rule to make target ‘debian/canonical-certs.pem‘, needed by ‘certs/x509_certificate_list‘

2. 报错：

Makefile:1194: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

2

参考 Ubuntu下通过源码编译方式升级内核

sudo apt install dwarves

3. 报错：

sed: can't read modules.order: No such file or directory
Makefile:1452: recipe for target '_modinst_' failed
make: *** [_modinst_] Error 2

参考 Linux内核编译错误

编译成功后重启
这时不能正常开机，只能升级系统。

二. 升级系统

升级系统后按上面重装显卡驱动
编译代码时报错：

CMake Error at CMakeLists.txt:3 (project) :
    No CMAKE_CXX_COMPILER could be found.

参考：
ubuntu20.04 cmake编译出错：No CMAKE_CXX_COMPILER could be found.

sudo apt install -y build-essential

这时系统是
