I just installed the latest OpenVINO toolkit for Mac. I'm getting the following error
[setupvars.sh] OpenVINO environment initialized

I thought I figured it out but was wrong so I am deleting what I thought fixed the issue.

Please check if your installation is complete, does file "/opt/intel/openvino_2020.1.023/opencv/lib/libopencv_ml.4.2.dylib" exist?

The file does exist but not in that directory. This could be due to the fact that I tried all 3 installation types and the last installation type was "user"
Joseph-Celi-MBP:lib josephceli$ pwd
/Users/josephceli/intel/openvino_2020.1.023/opencv/lib
Joseph-Celi-MBP:lib josephceli$ ll libopencv_ml.4.2.dylib
lrwxrwxr-x 1 josephceli staff 24 Jan 27 10:56 libopencv_ml.4.2.dylib -> libopencv_ml.4.2.0.dylib

So you have to activate environment for installation in user directory: ". /Users/josephceli/intel/openvino_2020.1.023/bin/setupvars.sh"

Maksim,
Yes, I had been doing that.

I can not reproduce the issue:

What is your OS version? Check LD_LIBRARY_PATH and DYLD_LIBRARY_PATH environment variables contents, at least one of them should contain path to opencv/lib directory. Check sizes of installed files.

Hello Joseph.
Can you please try the workaround from this thread - https://github.com/opencv/opencv/issues/14353

Just noticed this last update. @Max - I will try the workaround and report back.

@Max - I appreciate the link but am still unsure how to take the information from those links and apply it to my machine to get around the fact that the OpenCV dynamic link library cannot be found at runtime. While the link above describes a similar problem from the Java environment it certainly appears to be exactly what I am seeing. I tried to manually update my environment, using the following snippet from the links provided above
if sys.platform == 'darwin': # https://github.com/opencv/opencv/issues/14351
if env is None:
env = os.environ.copy()
if 'DYLD_LIBRARY_PATH' in env:
env['OPENCV_SAVED_DYLD_LIBRARY_PATH'] = env['DYLD_LIBRARY_PATH']
I still see the same error

Hi Joseph.
Can you please try it with "python3" alias instead of just "python"? Or you could also try upgrading python over to 3.7 version.
I see the same behavior on my machine with "python" as python 2.7, but everything's fine with "python3" as python 3.7.
Best regards, Max.
