from openvino.model_zoo.model_api.performance_metrics import PerformanceMetrics

Hi.

I am testing colorization_demo.py from open_model_zoo repo.

cmd : 

python colorization_demo.py -i ~/code/datasets/dish.jpg \

-m public/colorization-v2/FP16/colorization-v2.xml

result :

error message is,

Traceback (most recent call last):
File "colorization_demo.py", line 30, in <module>
from images_capture import open_images_capture
File "/home/pi/code/open_model_zoo/demos/common/python/images_capture.py", line 9, in <module>
from openvino.model_zoo.model_api.performance_metrics import PerformanceMetrics
ModuleNotFoundError: No module named 'openvino.model_zoo.model_api'

So, I tried to debug the file in the VSCode.

Then error message is  same.

For workaround, assign path to 'PerformanceMetrics' to sys.path and modify import statement is working like follows.

sys.path.append('/home/pi/code/notebooks/common/python/openvino/model_zoo/model_api')

from performance_metrics import PerformanceMetrics

But this may not be the solution.

My environment is,

  - Windows WSL, Ubuntu 20.04

Thanks.

@gb8 according to OMZ demos description you need to properly initialize environment to run demos, in particular you need to install OMZ Model API python component (to run python based demos), this can be achieved with simple command:

pip install <omz_dir>/demos/common/python

[gb8 · Accepted solution]

pip install <omz_dir>/demos/common/py 

solved the problem.

Thanks a lot.

note) 

in the install guide page(https://docs.openvino.ai/latest/omz_demos.html), model_api install guide link you send   seems to be broken.

it leads to https://docs.openvino.ai/latest/common/python/openvino/model_zoo/model_api/README.md#installing-python*-model-api-package, and 404 message shows.
