Python Demo - Missing OpenCV Post-OpenVINO installation? (Mac OSX 10.15.5)

raymondlo84 — Wed, 16 Sep 2020 21:20:45 GMT

During the OpenVINO installation I see the OpenCV was selected as part of the installation, but did it setup the packages for the Python? I try to do simple, import cv2 with python3 and it's not working, so how can I run the demo scripts as they all have the same dependencies?

I did run the setupvar.sh before running the Python.

Is there a tutorial on how to run those Python demos? This is not showing me the setup and so?

Hi Raymond,

That happens because OpenCV is not installed. It seems you have Python 3.8.2 installed. Refer this link for OpenVINO installation: https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_macos.html

Follow the installation steps and make sure you meet the system requirement needed.

Software Requirements:

Cmake 3.9 or higher

Python 3.5 - 3.7

Apple Xcode* Command Line Tools

(Optional) Apple Xcode* IDE(not required for OpenVINO, but useful for development

Best Regards,

Aznie

Thank you for the reply. Yes, I checked and the Python 3.8 is the root cause of many of these issues. Oddly as I didn't get any warnings from the installation from the dependency check. Instead, the Python 3.8 was installed automatically by the openvino toolkit installer (FYI my machine was brand new and Python was never installed).

However, is there any instructions on how to run the code in the python_demo folder? I ran human_pose_estimation_3d_demo, and it seems the pose_extractor is missing?

Thank you!

Ok, I found it. So the build flag for python + setting path was not very clear to me at all. I am glad this was discussed already however. (I'm not alone kinda feeling).
