Face Recognition - File can't be opened for writing

KirAsh4

Looks like it doesn’t have permission to open your trainingFile:

model.load(json.loads(sys.argv[1])[“trainingFile”])
cv2.error: /build/opencv-ISmtkH/opencv-2.4.9.1+dfsg/modules/contrib/src/facerec.cpp:325: error: (-2) File can’t be opened for writing! in function load

Notice the File can't be opened for writing message.

Wherever it’s trying to create that file, the main process running MM can’t write to that location.

Probably it does not even exist in that path. Be sure to add the training file path to the conduct of put it in the module folder.

The XML file is located in the module path mmm-facial-recognition.
I will answer more precisely when I’m back hat home

So, my internet is back after a day :D

I reinstalled the module with deleting & cloning it again.

The training.xml is located in

/home/pi/MagicMirror/modules/MMM-Facial-Recognition

I installed open cv with

sudo apt-get install libopencv-dev python-opencv

after this, i went into the folder

MMM-Facial-Recognition

and typed

sudo npm install

I still get the same error MSG :(

i also changed the rights on the training.xml to Anyone/Anyone/Anyone

please help <3

@feuerball try putting it somewhere else and set the trainingFile setting in your config :)

feuerball
