Label multiple tasks at once about label-studio

[deppp]

@mrijken thanks for bringing that up. Interesting idea, but I'd assume it can only work for classification and not the region labeling?

We will be updating the data manager to something more powerful in the upcoming version and will consider how to add that, probably after we finalize the images support.

I too would like some form of multiple task management - perhaps a simple first step might be something along the lines of:

• allow arrays in the backend config.json for each task.

Something like:

• allow an array in label_config key within the backend/config.json file - letting a custom UI per task be created.
• allow an array of task.jsons in the input_path key for the backend/config.json file
• allow an array of output folders in the output_dir key of backend/config.json file, allowing a 1:1 mapping of task input to output.

A 3 task setup might look like:

more config.json 
{
  "title": "Synopsis - Label Studio",
  "port": 8200,
  "debug": true,

  "label_config": ["../examples/synopsis_image/config_task1.xml", 
                             "../examples/synopsis_image/config_task2.xml", 
                             "../examples/synopsis_image/config_task3.xml"],
  "input_path": ["../examples/synopsis_image/some_taskname.json",
                          "../examples/synopsis_image/some_other_taskname.json",
                          "../examples/synopsis_image/last_task.json"],

  "output_dir": ["../examples/synopsis_image/completions/task1",
                          "../examples/synopsis_image/completions/task2",
                          "../examples/synopsis_image/completions/task3"],

  "instruction": "Choose a task, and complete the instructions in the UI shown",
  "allow_delete_completions": true,

  "editor": {
    "build_path": "../build/static",
    "debug": false
  }
}

Clearly there'd have to be a check to ensure each label_config, input_path and output_dir had matching array sizes.

Finally, Some simple UI to chose which task, which could be even some sort of URL component string like

http://192.168.1.183:8200/?taskname=some_taskname&task_id=1

Just thinking aloud. Thanks again for this project!

are we supporting labeling multiple task at once? (only for image classfication)

@NandaBalakrishnan We are very close to it. I think it will be in one release.
