I have created a model "in a project where I am trying to detect in real time “---------------------------------------------------------------------------
error Traceback (most recent call last)

68 image = infer()

—> 70 cv2.imshow(‘image’, image)

73 print((1/(time.time()-start)), " fps”)

error: OpenCV(4.6.0) D:\a\opencv-python\opencv-python\opencv\modules\highgui\src\window.cpp:967: error: (-215:Assertion failed) size.width>0 && size.height>0 in function ‘cv::imshow’"

I get an error like "{
“__comment1”: “Obtain these values via Roboflow”,
“ROBOFLOW_API_KEY”: “########”,
“ROBOFLOW_MODEL”: “biscuit_detct”,
“ROBOFLOW_SIZE”: 416,

I can not solve this error? I can send the complete code.

Can you help me? .
Thanks for your help.

The error message you’re seeing is typically due to OpenCV’s imshow function not receiving a valid image. This could be because the image is not being loaded correctly or the image path is incorrect.

In the context of Roboflow, if you’re using a webcam or other video source for real-time detection, you might encounter issues if the video source is not found or not accessible. As mentioned in the Roboflow blog post, if you encounter an error like assert cap.isOpened(), f'Failed to open {s}' and AssertionError: Failed to open 0, it indicates that your camera was unable to be found. You can try reconnecting your camera or changing the source argument to detect.py. To try changing the source argument, use --source 1 with detect.py instead of --source 0.

If you’re still encountering issues, please ensure that your image or video source is correctly set up and accessible.
