Hi everyone,

I try to run sample code with AVX2, but I cannot find any "libcpu_extension_avx2.so" file

Intel OpenVINO Tutorial Videos ( https://www.youtube.com/watch?v=fPPcYeFbmiA&list=PLDKCjIU5YH6jMzcTV5_cxX9aPHsborbXQ&index=43 ) 4:38

  • OS : Windows 10 home
  • OpenVINO : 2019.3.379

AVX2, SSE4.2 and AVX512 are supported on my CPU.

How can I get the 'libcpu_extension_avx2.so' file?

or how to use it ?

Thanks!!!

Hi Liao,

Since you are using Windows, you can find the cpu extension dll file from:

openvino_2019.3.379\deployment_tools\inference_engine\bin\intel64\Release\cpu_extension_avx2.dll

The OpenVINO Tutorial Video is demonstrated on Linux OS.

Also, you can install the latest version of OpenVINO (2020.1) where CPU extensions library was removed as they were moved into the plugin.

Regards,

Jaivin

Hello Liao,

 

I come across this topic, I need to run a face detection model from github and it needs to have this cpu_extension_avx2.dll. I am using OpenVINO 2020 R4, can you show me the path where is this file located in?

 

Thanks for the help.
