Yes, after installing all the dependencies I ended up with this error code : FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal.

tensorflor-models/posenet has been updated so you need to update code.

just checked my package.json

"dependencies": {
    "@tensorflow-models/posenet": "^1.0.3",
    "@tensorflow/tfjs": "^1.1.2",
    "@tensorflow/tfjs-node": "^1.1.2",
    "botkit": "^4.0.2",
    "canvas": "^2.5.0",
    "rollup": "^1.13.1"
  }

I ended up uninstalling everything and reinstalling. But now when I run the code I get " (node:87485) UnhandledPromiseRejectionWarning: TypeError: Cannot create property 'architecture' on number '0.75'" which seems to be an error within posenet. maybe not everything is completely installed correctly? what do you think thank you for the help

It's because posenet api has been updated in version 2.0. See:
github.com/tensorflow/tfjs-models/...

Example new loading code:

const net = await posenet.load({
  architecture: 'MobileNetV1',
  outputStride: 16,
  inputResolution: 513,
  multiplier: 0.75
});

Can you please add video inference support for posenet?

0xkoji • Dec 12 '19 • Edited

sorry i don't have time now.
i recommend you to check tfjs repo and dan's repos dev.to/oveddan since he is the peron who has implemented posenet to tfjs.
my code is outdated.

@gaelguedia
can you tell me your os version, nodejs version, npm/yarn and your package.json's dependencies

The above error was on windows 10, js 10. The issue seems to be related to canvas dependency. It's not easy to have it running on windows. It's easier on ubuntu especially easier to install cairo dependencies for Jpg/jpeg support
