Hi Heebahsaleem,

The encountered error is due to there is some conflict with OpenCV. May I know which OpenCV you’re using?

>>> import cv2
>>> cv2.__version__
'4.5.3-openvino'

Hi Heebahsaleem,

Where do you download the OpenCV 4.5.3-openvino?

I am able to run OpenCV with OpenCV 4.5.3-openvino, which included in Intel® Distribution of OpenVINO™ toolkit 2021.4.2.

Please ensure that you update OpenVINO™ environment variables by running the command below before importing OpenCV.

source /opt/intel/openvino_2021/bin/setupvars.sh

Peh

Hi Peh_Intel

Thank you for your reply.

I did as you said, but nothing works. I am really new to OpenVino.

As per the error, I have also tried installing libgtk2.0-dev and pkg-config, but it didn't work.

Your help will be highly appreciated.

Hi Heebahsaleem,

Can you try testing the basic OpenCV function with OpenCV 4.5.3-openvino?

Try with the following commands:

1. source /opt/intel/openvino_2021/bin/setupvars.sh
2. python3
3. import cv2
4. image = cv2.imread("AnyPathToAnImage.jpeg")
5. cv2.imshow("Image",image)
6. cv2.waitKey(0)

Hi Heebahsaleem,

For OpenVINO™ 2021.4.2, it only supports Python 3.6 - 3.8.

To proceed to use Python 3.11, you have to install OpenVINO™ 2023.2. For OpenVINO™ 2023.2, OpenCV is not include in the archives. However, you can download OpenCV package, pip install opencv-python .

[heebahsaleem]

thank you for your reply.

Yes, that's correct that OpenVino 2021.4.2 only supports Python 3-6 3.8 and hence I have installed Python version 3.8.

I do not want to use OpenVino 2023.2 version, because as per the documentation there is no blob converter for this version and I may have to use some tags which might not work, therefore 2021 could work right away.

Hi Heebahsaleem,

From your last screenshot, I noticed that you're importing Python 3.11.5.

Can you try creating a virtual environment and re-run OpenCV?

1. python3 -m venv openvino_env
2. source openvino_env/bin/activate
3. source /opt/intel/openvino_2021/bin/setupvars.sh
4. pip install numpy
5. python3
6. import cv2
7. image = cv2.imread("AnyPathToAnImage.jpeg")
8. cv2.imshow("Image",image)
9. cv2.waitKey(0)

Hi Peh_Intel

After lot of multiple attempt, I am able to solve the issue by uninstalling libtiff.

Thank you for your time and help^^
