Run Live Object Detection with OpenVINO in WSL2 Ubuntu 20.04

[RGVGreatCoder]

I come to realize that the OpenVINO demos run in a software (I just learned) called Jupyter Notebook. Sorry for learning this a bit too late.

However, I need to run the "Live Object Detection with OpenVINO": (https://docs.openvino.ai/latest/notebooks/401-object-detection-with-output.html) in my WSL2 Ubuntu 20.04 machine. I will also need to try this demo in a Raspberry Pi 4 device where I will not be able to install (nor run) Jupyter Notebook in it...

To begin trying to run the demo in my WSL2 Ubuntu 20.04 machine, I first downloaded the content in this github: (https://github.com/openvinotoolkit/openvino_notebooks) and then ran requirements as follows:

python -m pip install --upgrade pip
pip install -r requirements.txt

All requirements installed, except it displayed the following errors:

ERROR: launchpadlib 1.10.13 requires testresources, which is not installed.
ERROR: tensorflow 2.4.4 has requirement absl-py~=0.10, but you'll have absl-py 1.0.0 which is incompatible.
ERROR: tensorflow 2.4.4 has requirement gast==0.3.3, but you'll have gast 0.4.0 which is incompatible.

ERROR: pytorch-lightning 1.5.9 has requirement setuptools==59.5.0, but you'll have setuptools 60.5.0 which is incompatible.

I then started creating a Python program in my WSL2 Ubuntu machine (using Visual Studio Code) and I notice it points to an error on the following line of code that imports the notebook_utils:

import notebook_utils as utils
>> ERROR: Import "notebook_utils" could not be resolvedPylancereportMissingImports

I notice later in the program, the "utils" alias library is used in the following line of code:

player = utils.VideoPlayer(source=source, flip=flip, fps=30)

Later in the program, the "player" object is used in the following lines of code:

player.start()
...
frame = player.next()
...
player.stop()

Questions:

1. Can the OpenVINO Notebook demos (like the "Live Object Detection with OpenVINO") run outside Jupyter Notebook as a regular python program?
2. Can you please suggest me another library like notebook_utils that I can try in my program outside of Jupyter Notebook?

Thank you in advance for your support and will be waiting for your reply.

Hi RGVGreatCoder,

Thank you for reaching out to us.

I was able to install Jupyter Notebook and ran the Live Object Detection with OpenVINO using WSL2 Ubuntu 20.04 without error:

Please ensure that you have followed the OpenVINO Notebook Ubuntu guide correctly especially concerning your Python virtual environment for the Jupyter Notebook installation.

Regarding your questions:

1. The Jupyter Notebook App is a server-client application that allows editing and running notebook documents via a web browser. Thus, the notebook documents such as the "Live Object Detection with OpenVINO" can only be run inside of the Jupyter Notebook App and cannot be performed as a regular python program.
2. The notebook_utils is used only inside of Jupyter Notebook app thus, there are no similar library available outside of the app.

I would recommend you to use the Object Detection demo from Open Model Zoo which is available in C++ and Python versions. The demos can be obtained from the Open Model Zoo GitHub repository in the open_model_zoo/demos/object_detection_demo/ directory.

For your information, Open Model Zoo demos doesn’t require Jupyter Notebook to run. You can follow this Getting Started with Demo script guide to give you a starting point for learning the OpenVINO™ workflow.
