Skeleton Tracking with PoseNet and Node for Max

This is so amazinggggg! Thanks Sam!

Hello Sam!
I have about 1000 uses for this - sooooo happy

One problem -
I keep getting a console error when installing dependencies - "NPM exited with non-zero code "1"at /Volumes/Macintosh HD/Users/(me)/documents/n4m-examples-master/posenet"

I am on a slow cellphone hotspot for my internet since the hurricane hit - Am betting the hotpsot is where to place the blame....

The readme inside the archive says "1. Install npm dependencies by clicking the indicated button. Since Electron's kind of big in size, this make take a while depending on your network environment. "

Finally now to the actual question - Will I have to wait til I can find a bigger internet pipe?

The demo I found on the posenet site works fab !

*Really* looking forward to exploring with this.. : )
cheers

Ouch! Sorry to hear that. Yeah, this could definitely be the issue. Maybe a request is timing out when trying to download Electron, or possibly the connection is being interrupted. There are a couple of things you could try to get some more information:

1. Check inside the posenet/ folder for any .log files. Maybe there's something in there that can give us a clue what's going on.
2. Try running `npm install` from the command line and see if there's any more information logged there. To do this you'd either need to install npm on your machine, or you'd need to use the npm binary that ships with Node for Max. On OS X your session might look like:

cd path/to/n4m-examples/posenet
/Applications/Max.app/Contents/Resources/C74/packages/Node\ For\ Max/source/bin/npm/bin/npm install

I'd be curious what prints to the console there. Let me know how it goes!

Hey Sam ! thanks so much for your help with this...
Inside the posenet folder there are "shorty" log files that all say this:

*********

The complete log file mentioned above ends like this.....
- I am picking it up right before the errors start - Can send you the full log file if you need.
no errors up to this point.

Weird. Yeah could be a network error---a JSON file doesn't download completely and so can't be parsed correctly. Not sure what to do really other than wait for a better connection.

you might also try npm install from the command line, like I suggested. Worth a shot anyway.

Hey Sam! I tried your suggestion above, here's what came back

Baffling - the Posenet demo web page works perfectly...
thanks much for your help

A note to add - i have noticed that when I hit the "install dependencies" in the maxpat,
inside the posenet folder it creates the folder "node_modules/.staging"

Inside of the .staging folder are many many subfolders, then after a few seconds all of the folders delete and the node_module folder is then left empty.

Log generated in the posenet folder is here:

Other projects in the n4m-examples folder seem to work and install dependencies correctly

Hey Sam!
It's working now ! : )

I deleted the Max8 app and reinstalled and all is good now. I can get data from the dict and the tracking is pretty good.
I THINK my problem was a bad internet connection at first, further compounded by clueless operator-error flailing with dependencies.

Now that I am up and running (THIS IS SOOO COOL) I have run across one small issue -

******** The issue:
IF I am not connected to internet when running the "main" patch - Start/Stop Posenet only opens up the Electron window with the text "Loading the Model" and does not proceed any further...

IF I am connected to the net, "Loading the model" comes up for a few seconds and then the Posenet window starts working properly. I can get all the pose data from the dict and all is well.

I can now disconnect the internet and close/restart the patch, or Quit/Restart Max and all works perfectly UNTIL the next reboot of my machine - then it starts all over....

***** the question:
I am assuming there is some file/data being brought down from the net that survives a Max restart but not a computer restart... Is there anyway to make this truly "Offline"?

Thanks so much for your help
cheers!
