Failed to create component 'vc.ril.camera' (1:ENOMEM)

[VedadTr]

Hi ! Love the module idea, and i was planning on using it on my project, but i have encountered some errors. They just might be a mistake on my side, since this is my first time working with Raspberry and Linux.

I have installed OpenCV, and im using Raspberry Pi 3 b+ with the regular camera module. I tested the camera using raspistill - o and it works.

To my understanding, i just make a new folder called dataset in module folder, make another folder with the person name, and fill it with images. Then i run the encode python script, which creates encodings.pickle ? The pickle file is there, but i did not edit the python script, was i supposed to ?

After adding the module in the Mirror Config file, i start the mirror via npm start, and get a black screen. Nothing happens when i point the camera, and the terminal shows this:

Here's the whole terminal log here too:

hi @VedadTr

Yes this encode.pickle file is then automatic generated on images in the subfolders. that sounds right.

about your second error. not sure whats happening there. can you send me your config of my module? did you installed opencv directly or with a virtual python environment? Did you test it if opencv is installed properly and python has access to it?

greets nischi

[VedadTr]

@nischi Thanks for the quick reply ! I installed open cv following your steps: https://pyimagesearch.com/2018/09/26/install-opencv-4-on-your-raspberry-pi/ Following the steps, i couldn't compile the program using make or make -j4, since the pi would always crash or display some errors.

So i installed OpenCV using - pip install opencv-python . I tested the installation using python3, import cv2, cv2.version. it seems to be installed just fine...

Now for the mirror config file, im dropping it in pastebin down below:

[VedadTr]

I manage to fix the problem by unplugging and plugging the camera on...

[nischi]

oh okay :) a reboot is always good :) but then i will close this issue
