using weka by docker

[elahia]

Hi, i'm using openface which is a package for detecting some features of human face, then i need to send this features to weka for classifying, i couldn't find any way to call weka in c++, so i decided to use docker, my goal is defining two containers, one contains openface which provide the input for weka and the other a container for weka,

so how can i use your docker file for this purpose??? thanks in advance

Hi Elahia, I have no knowledge of Openface, but after having a quick read of your gh issue: https://github.com/TadasBaltrusaitis/OpenFace/issues/409 I imagine you could use docker-compose to help you . Am I correct in that openface outputs csv files you would like to process ? if so you could create a volume that the containers share. You might also find you have to build your own image based off my weka image. using a dockerfile and reference that in docker-compose. Finally, depending on your use case you might find it bestto use weka over the command line

Hi James, Thank you for your reply, actually, now i stick in one step before using weka! So let me please pass this step then i will go for the details you provide me,

Thank you so much,

Hi James, I changed the scenario of my prj someway that there is no need to calling weka! but still i have some question about docerizing my prj! So please let me make an overview of my prj for you at first, then i will ask you my questions!

1. openface will provide me with face data by a csv file and as it is running on visualstudio2015, then i need to create an image which is able to run vs2015, Am i correct?

2. I wrote a program for analyzing the voice of the user in Matlab, so i need another container which is able to run Matlab and my code,

3. the result of openface and Matlab code has to be sent to a python program for the final decision, so i need another container which runs python!

so totally i need 3 containers with a shared volume to share the variables and data and a dockercompose file to use these three images! Atually, i know what should i do but i don't know HOW to start!! so can you please help me to find my way! in addition, i'm on ubuntu 14.04,

Best Regards Elahe

Hi Elahe,

1st if you haven't already, you'll need to have docker and docker-compose installed. I find the easiest way to do that is by using this script , although I have never tried this on 14.04.

2nd you will need to create a docker-compose.yml As a start point yours might look something like this:

version: '3'
services:
  matlab:
    volumes:
      - data-volume:/data
    build:
      context: ./matlab
      dockerfile: Dockerfile-matlab
  python:
    image: python
    volumes:
      - data-volume:/data
  openface:
    image: openface
    volumes:
      - data-volume:/data

volumes:
  data-volume:

Which you could run by docker-compose up what language are you using in vs2015, you will need to use / write a docker image so you can run it directly without vs2015.

Thanks James

Dear James, Thank you for your comment, Yes i already installed Docker and docker-compose, about the used language in vs2015 the openface is written in c++, for running matlab in docker i realized that i need a runtime version of my matlab code, which make all its functions and dependencies available, so i think for openface also i need to make it as an app and then try to run that app in docker! Did you hear anything about it? because openface is a big and complex package with lots of dependencies subfolders and etc, how docker can manage all these things!
