The training is working fine but the Module doesnot works when used in config.js Please check the issue !

Other modules are also there but i think no need to show here as the error in the log is from Face recognition module

Same problem. How did you solve this????

dimitrystd commented 5 years ago

Me too. JIC

ejwessel commented 5 years ago

+1 having this issue

Edit: I googled around for the error regarding PythonShell is not a constructor and came across: https://github.com/extrabacon/python-shell/issues/154

It suggests using curly brackets around PythonShell const {PythonShell} = require("python-shell");

shayfer commented 5 years ago

I have tried that as well but now I get a new error.

  • Open node_helper.js var option = {pythonPath: 'python'} const pyshell = new PythonShell('modules/' + this.name + '/facerecognition/facerecognition.py', option, { mode: 'json', args: [JSON.stringify(this.config)]});

Do you mean add var options? It does not work for me. :(

roudaille commented 5 years ago

same issue over here. Same node_helper.js tested with MMM-Facial-Recognition-OCV3 is working fine.

fpdrozd commented 5 years ago

Hi, I installed an older version of python-shell (0.4.0 - released 3 years ago) and it works without modifying the node_helper.js file. There had to be some breaking changes.

Hi! How did you install an older version of python shell to make the MMM-Facial-Recognition work?

Sumrag commented 5 years ago

I have tried that as well but now I get a new error. Where you able to solve the issue? My output is the same as yours when I insert the curly brackets.

fpdrozd commented 5 years ago

@Sumrag You can install this specific version of python-shell by this command: npm install python-shell@0.4.0
