Canvas Install Errors about node-red-contrib-face-recognition HOT 18 CLOSED

Hmm, interesting. I haven't played with this repo in a while. Maybe canvas has updated.

What platform are you using for this. A raspberry pi?

from node-red-contrib-face-recognition.

Yes, on a Pi.

from node-red-contrib-face-recognition.

I have also tried a direct install of canvas and with the --build-from-source option as well. I am using sudo but still getting permission errors.

from node-red-contrib-face-recognition.

This sounds like a canvas issue then, not so much this repo. I just popped over to the canvas GitHub page, and I can't see any open issues regards a pi install.

I don't usually built with the pi for these reasons, its just annoying to debug. It certainly seems though from your description that's it's just permission errors so maybe googling around on how to build the canvas package could bring up some more results?

When I get some spare time I want to install this on a pi so I can use it as a remote server. Until then I'm afraid I'm not going to be much help.

Just having a look around, did you follow this at all?

from node-red-contrib-face-recognition.

Yes. I have tried everything that I am able to find via searching. It is definitely Canvas itself.
When I find a solution I will post it here.

from node-red-contrib-face-recognition.

Ah annoying,

Any chance you can post a log of the install, see if there is any relevant info in that?

from node-red-contrib-face-recognition.

I read somewhere that you need to be root to install canvas. I tried that and it worked.

Everything in the log was simple permission errors to create sub directories. Even though I was using Sudo.

Also, in your README.md you might want to mention the additional nodes that need to get installed for your flow to work. Took me a little bit to find the Image one.

Apologies for this, I thought I had for this repo, but ust have been thinking of another. Ill fix that up now.

Good news. Does this allow you to run the node correctly now?

yes

Awesome, glad its working then. I will close and pin this for others. Thanks for the info.

from node-red-contrib-face-recognition.

Además, en su archivo README.md es posible que desee mencionar los nodos adicionales que deben instalarse para que su flujo funcione. Me llevó un poco encontrar la imagen.

please, where is the readme.md file?

Have a look at the other issues for canvas install errors.

thank you so much for your answer,
tried root npm but nothing good. on ubuntu there is no problem but in pi4.... i could not make it

from node-red-contrib-face-recognition.

I have been meaning to look into this as I have migrated all of my operations to embedded recently (mostly pi 4).

If it works on linux but not the Pi, my guess is its the ARM architecture that's the issue.

Seems there are a few issues related to ARM over on the canvas repo which might suggest this is the error as well:

Automattic/node-canvas#1662

When I first built this node, I really tried to get rid of canvas to make it more portable, but unfortunately Face-API.js uses its functionality with no way around it.

In the mean time if you manage to find a solution feel free to post it back here, or make a pull :)

Hello, me again :) Thought I'd take a look at this.

I'm running the latest node-red docker image (official) and just being root isn't enough. There is no canvas (or issues building it) on alpine (the distro the node-red container runs on).

To fix issues open a terminal into the node-red container and run:

apk add --no-cache \
    python \
    g++ \
    build-base \
    cairo-dev \
    jpeg-dev \
    pango-dev \
    musl-dev \
    giflib-dev \
    pixman-dev \
    pangomm-dev \
    libjpeg-turbo-dev \
    freetype-dev \
    && npm install [email protected]

You can then install node-red-contrib-face-recognition into node-red:

Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.

Hurray! Yet to confirm the nodes actually work of course..but...baby steps!

Edit:

Terrifying!
