Error with OpenCV module (Computer Vision)

[Ketechi]

Hello everyone,

I am trying the new Gtuner release with Computer Vision but I am running into an issue. So far I have been able to install python.dll fine but it appears the OpenCV is not working at all.

I installed OpenCV trough pip install I installed OpenCV with the following command "pip install target=D:\Gtuner\_Python opencv-python" as you can see on this image I was able to install OpenCV on that directory.


However, on GtunerIV it shows that OpenCV is not recognized. You can see it in the following image.


Is there something I am missing?

Thanks in advance for the help.

For me the opencv path is like this:
C:\Users\username\AppData\Local\Programs\Python\Python38\Lib\site-packages
The file is here: C:\Users\username\AppData\Local\Programs\Python\Python38\Lib\site-packages\cv2\cv2.cp38-win_amd64.pyd
Not sure if GTuner or python needs the opencv to be in Lib\site-packages ? Maybe try to add that cv2 path to your PATH env ?

Correct, Gtuner expects the default Python directory structure (Lib and Lib\site-packages).

Thanks, I was able to make it work. I followed the advice and installed pip on "C:\Users\ME\AppData\Local\Programs\Python\Python37\Lib\site-packages".

Now OpenCV is being recognized.


In case it helps anyone what I had to do when installing OpenCV and Win32Api was the following:

For OpenCV: pip install --target=C:\Users\[your username]\AppData\Local\Programs\Python\Python[your version of python]\Lib\site-packages opencv-python

For Win32Api: pip install --target=C:\Users\[your username]\AppData\Local\Programs\Python\Python[your version of python]\Lib\site-packages pywin32

Glad you got working and thank you for sharing your findings.

I fixed the issue of my cv2 not being recognized but now I am encountering a new issue when just trying to do a visual input check:
GCV Error: _win_os_check()
File "C:\Users\garri\AppData\Local\Programs\Python\Python38\Lib\site-packages\numpy\__init__.py", line 302, in _win_os_check
raise RuntimeError(msg.format(__file__)) from None
RuntimeError: The current Numpy installation ('C:\\Users\\garri\\AppData\\Local\\Programs\\Python\\Python38\\Lib\\site-packages\\numpy\\__init__.py') fails to pass a sanity check due to a bug in the windows runtime. See this issue for more information: https://tinyurl.com/y3dm3h86
numpy.core.multiarray failed to import

Please help! I have tried Python 3.8 and 3.9. Thanks

The solution is first remove your current numpy install and use numpy 1.18.1

Code: Select all

pip install numpy==1.18.1

pip install numpy==1.18.1

You are a life saver, thank you!
Here is the terminal command if anyone needs it:

python -m pip install --target=C:\Users\[Username]\AppData\Local\Programs\Python\Python[Version]\Lib\site-packages numpy==1.18.1 --upgrade

example:
python -m pip install --target=C:\Users\myUsername\AppData\Local\Programs\Python\Python38\Lib\site-packages numpy==1.18.1 --upgrade
or if you are in a python ide then its just
pip install --target=C:\Users\myUsername\AppData\Local\Programs\Python\Python38\Lib\site-packages numpy==1.18.1 --upgrade
