PyBossa demo project tagging pictures

The project has four main files:

  • project.json: a JSON file that describes the project.
  • a Markdown file with a long description of the project.
  • template.html: the task presenter where the user/volunteer will do the image tagging.
  • tutorial.html: a simple tutorial for the volunteers.

Testing the project

You need to install the pybossa-pbs. If you don't have a virtual environment, we recommend you to create one, and activate it:

    $ virtualenv env
    $ source env/bin/activate

Then, you can install pybossa-pbs:

    $ pip install pybossa-pbs

Creating an account in a PyBossa server

Now that you've all the requirements installed in your system, you need a PyBossa account:

  • Create an account in your PyBossa server (use Crowdcrafting if you want).
  • Copy your API-KEY (you can find it in your profile page).

Configure pybossa-pbs command line

PyBossa-pbs command line tool can be configured with a config file in order to avoid typing the API-KEY and the server every time you want to take an action on your project. For this reason, we recommend you to actually create the config file. For creating the file, follow the next steps:

    $ cd ~
    $ editorofyourchoice .pybossa.cfg

That will create a file. Now paste the following:

apikey: yourapikey

Save the file, and you are done! From now on, pybossa-pbs will always use the default section to run your commands.

Create the project

Now that we've everything in place, creating the project is as simple as running this command:

    $ pbs create_project

Adding some tasks

Now we can add some tasks. The project comes with a set of sample tasks that you can use:

  • taggingpictures_task.json: a JSON file with some tasks

Using a JSON or CSV file for adding tasks

This is very simple too, thanks to pbs:

    $ pbs add_tasks --tasks-file taggingpictures_task.json

Or, alternatively, use a CSV file:

    $ pbs add_tasks --tasks-file taggingpictures_task.csv

You'll get a progress bar with the tasks being uploaded. Now your project has some tasks in the server to be processed by the volunteers.

Finally, add the task presenter, tutorial and long description

Now that we've some data to process, let's add to our project the required templates to show a better description of our project, to present the tasks to our users, and a small tutorial for the volunteers:

    $ pbs update_project

Done! Now you can do image pattern recognition problems in the PyBossa server.

NOTE: we provide templates also for Bootstrap v2 in case your PyBossa server is using Bootstrap2 instead of Bootstrap3. See the rest of the files.


We recommend that you read the section: Build with PyBossa and follow the step by step tutorial.

NOTE: This application uses the pybossa-client in order to simplify the development of the application and its usage. Check the documentation.
