Docker Image

You can also attempt to install candis via Docker as follows:

$ docker pull helikarlab/candis

... and simply run the image optionally mapping the port 5000.

$ docker run -p 8888:5000 helikarlab/candis

OR

After cloning the repository, build from the updated Dockerfile and docker-compose.yml:

For development:

$ ./manage up -d --build

For production:

$ CANDIS_ENVIRONMENT=production ./manage up -d --build

Then go to localhost:5000 in your browser to open the app.

Other Commands:

$ ./manage [service] [command]

$ ./manage db backup			 		# Backup the database
$ ./manage db restore /path/to/backup	# Restore a snapshot
$ ./manage db backups 				 	# List all backups

Usage

Launching the RIA (Rich Internet Application)

via CLI

$ candis

OR

$ python -m candis

via Python

>>> import candis
>>> candis.main()

Using the CLI (Command Line Interface)

$ candis --cdata path/to/data.cdata --config path/to/config.json

Using the Jupyter Notebook from inside the docker container

• Starting the jupyter notebook server inside the candis app container

$ docker-compose exec app jupyter notebook --ip 0.0.0.0 --no-browser --allow-root

Features

• Converting a CDATA to an ARFF file

  >> import candis
  >> cdata = candis.cdata.read('path/to/data.cdata')
  

  Then, simply use the CData.toARFF API:

  >> cdata.toARFF('path/to/data.arff')
  

• Running a Pipeline.

  >> pipe = candis.Pipeline()
  >> pipe.run(cdata)
  >> while pipe.status == candis.Pipeline.RUNNING:
  ..     # do something while pipeline is running
