Unable to computer vision in jupyter lab

Good days everyone

 

I was doing my project related to computer vision to detect the car plate. Hence I start by calling out the image and displaying it. I am just using a simple function: cv2.imshow("Image",img). However, it turns out in the kernel died.

 

How can this be resolved?

Hi Wen_Jie,


Thanks for reaching out, using cv2.imshow on Intel Developer Cloud for the Edge will not work as you are submitting jobs to the Edge nodes and not on the node running the Jupyter Notebook. Please take a look at the sample applications, we provide samples to submit a video for inference and save the results in a .webm file that can be viewed using the videoHTML function as follows:


videoHTML('Intel CPU + Intel NCS2', 

     ['results/ncs2/output_{}.webm'.format(id_ncs2)], 'results/ncs2/stats_{}.txt'.format(id_ncs2))

Hope this helps!

Hi all

 

I also have a doubt that: Can DevCloud for edge perform a real-time video stream using a webcam in jupyter lab by calling function  cv2.VideoCapture(0) ? 

 

 

Thank you
