Several questions regarding to the official docker image?

Jump to solution

There are several questions I would like to ask:

1. I used ubuntu18_dev:2020.2 image and I got the following file is not found:

    /opt/intel/openvino/deployment_tools/inference_engine/lib/intel64/libcpu_extension_sse4.so

    This file was in the old docker image so I am not sure what is the best way to deal with this.

    EDIT: I tried to replace libcpu_extension_sse4.so with libMKLDNNPlugin.so and then I got a new error:

              RuntimeError: dlSym cannot locate method 'CreateExtension': /opt/intel/openvino/deployment_tools/inference_engine/lib/intel64/libMKLDNNPlugin.so: undefined symbol: CreateExtension

2. I used ubuntu18_dev:2019_R3.1 image and I got the following error:

$ python3
Python 3.6.8 (default, Oct  7 2019, 12:59:55) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: libSM.so.6: cannot open shared object file: No such file or directory

According to some forum post, I need to install additional package in order to make it work. However I got the permission error because I don't have sufficient privileges to install package. How could I do that?

Lastly may I add a comment. I checked the OpenVino Docker page and I find 4 image description is the same. I couldn't find the right image until I try one by one. Is it possible that the description can be updated?

Thanks for the help

Hi,

1. CPU extensions are moved to plugin since OpenVINO release 2020.1. The extensions are loaded automatically while loading the CPU plugin, hence 'add_extension' need not be used.

2. Please verify that you have Set the Environment Variables.

Also, thank you for reporting the concerns that helps to make OpenVINO a better Intel software product. 

Regards,

Jaivin

Thanks a lot. Yeah removing CPU-related argument solves the problem.

 

And since the latest docker image solves my problem. So I am not going to test the 2019_R3.1. But thanks for answering the question.
