Argilla on Spaces

Argilla is an open-source, data labelling tool, for highly efficient human-in-the-loop and MLOps workflows. Argilla is composed of (1) a server and webapp for data labelling, and curation, and (2) a Python SDK for building data annotation workflows in Python. Argilla nicely integrates with the Hugging Face stack (`datasets`, `transformers`, `hub`, and `setfit`), and now it can also be deployed using the Hub’s Docker Spaces.

Visit the Argilla documentation to learn about its features and check out the Deep Dive Guides and Tutorials.

In the next sections, you’ll learn to deploy your own Argilla app and use it for data labelling workflows right from the Hub. This Argilla app is a self-contained application completely hosted on the Hub using Docker. The diagram below illustrates the complete process.

##
Deploy Argilla on Spaces

You can deploy Argilla on Spaces with just a few clicks:

**IMPORTANT NOTE ABOUT DATA PERSISTENCE:** You can use the Argilla Quickstart Space as is for initial exploration and experimentation. For **longer use in small-scale projects, activate the paid persistent storage option**. This prevents data loss during Space restarts every 24 hours. If not using persistent storage, safeguard your data with Argilla Python SDK by storing it elsewhere. In this case, we gently remind you that the responsibility for maintaining your data's safety becomes yours.

You need to define the Owner (your personal account or an organization), a Space name, and the Visibility. To interact with the Argilla app with Python, you need to set up the visibility to `Public`.

If you want to customize the title, emojis, and colors of your space, go to "Files and Versions" and edit the metadata of your README.md file.

Once you have created the Space, you’ll see the `Building` status and once it becomes `Running` your space is ready to go if you don’t see the Argilla login UI refresh the page.

The Space is configured with two users: argilla and admin with the same default password: 12345678. If you get a 500 error after login, make sure you have correctly introduced the user and password. To secure your Space, you can change the passwords and API keys using secret variables as explained in the next section.

##
Set up passwords and API keys using secrets (optional)

For quick experimentation, you can jump directly into the next section. If you want to secure your space and for longer-term usage, setting up secret variables is recommended.
## Setting up secret environment variables

The Space template provides a way to set up different optional settings focusing on securing your Argilla Space.

To set up these secrets, you can go to the Settings tab on your created Space. Make sure to save these values somewhere for later use.

The template Space has two users: `admin` and `argilla`. The username `admin` corresponds to the root user, who can upload datasets and access any workspace within your Argilla Space. The username `argilla` is a normal user with access to the `argilla` workspace.

The usernames, passwords, and API keys to upload, read, update, and delete datasets can be configured using the following secrets:

- `ADMIN_USERNAME`: The admin username to log in Argilla. The default admin username is `admin`. By setting up a custom username you can use your own username to log in to the app.
- `ADMIN_API_KEY`: Argilla provides a Python library to interact with the app (read, write, and update data, log model predictions, etc.). If you don’t set this variable, the library and your app will use the default API key i.e. `admin.apikey`. If you want to secure your app for reading and writing data, we recommend you to set up this variable. The API key can be any string of your choice. You can check an online generator if you like.
- `ADMIN_PASSWORD`: This sets a custom password to log in to the app with the `argilla` username. The default password is `12345678`. By setting up a custom password you can use your own password to log in to the app.
- `ANNOTATOR_USERNAME`: The annotator username to log in to Argilla. The default annotator username is `argilla`. By setting up a custom username you can use your own username to log in to the app.
- `ANNOTATOR_PASSWORD`: This sets a custom password to log in to the app with the `argilla` username. The default password is `12345678`. By setting up a custom password you can use your own password to log in to the app.

The combination of these secret variables gives you the following setup options:

1. I want to avoid that anyone without the API keys adds, deletes, or updates datasets using the Python client: You need to setup `ADMIN_PASSWORD` and `ADMIN_API_KEY`.
2. Additionally, I want to avoid that the `argilla` username deletes datasets from the UI: You need to setup `ANNOTATOR_PASSWORD` and use the `argilla` generated API key with the Python Client (check your Space logs). This option might be interesting if you want to control dataset management but want anyone to browse your datasets using the `argilla` user.
3. Additionally, I want to avoid that anyone without password browses my datasets with the `argilla` user: You need to setup `ANNOTATOR_PASSWORD`. In this case, you can use the `argilla` generated API key and/or `ADMIN_API_KEY` values with the Python Client depending on your needs for dataset deletion rights.

Additionally, the `LOAD_DATASETS` will let you configure the sample datasets that will be pre-loaded. The default value is `single` and the supported values for this variable are:

1. `single`: Load single datasets for TextClassification task.
2. `full`: Load all the sample datasets for NLP tasks (TokenClassification, TextClassification, Text2Text)
3. `none`: No datasets being loaded.

##
How to upload data

Once your Argilla Space is running:

1. You need to find the Space Direct URL under the “Embed this Space” option (top right, see screenshot below).
2. This URL gives you access to a full-screen Argilla UI for data labelling. The Direct URL is the api_url parameter for connecting the argilla Python client in order to read and write data programmatically.
3. You are now ready to upload your first dataset into Argilla.

Argilla Datasets cannot be uploaded directly from the UI. Most Argilla users upload datasets programmatically using the argilla Python library but you can also use Argilla Data Manager, a simple Streamlit app.

For uploading Argilla datasets, there are two options:

1. You can use the argilla Python library inside Jupyter, Colab, VS Code, or other Python IDE. In this case, you will read read your source file (`csv`, `json`, etc.) and transform it into Argilla records. We recommend to read the basics guide.
2. You can use the no-code data manager app to upload a file and log it into Argilla. If you need to transform your dataset before uploading it into Argilla, we recommend the first option.

To follow a complete tutorial with Colab or Jupyter, check this tutorial. For a quick step-by-step example using the `argilla` Python library, keep reading.

First, you need to open a Python IDE, we highly recommend using Jupyter notebooks or Colab.

Second, you need to `pip` install `datasets` and `argilla` on Colab or your local machine:

    pip install datasets argilla

Third, you need to read the dataset using the `datasets` library. For reading other file types, check the basics guide.

    from datasets import load_dataset

    dataset = load_dataset("dvilasuero/banking_app", split="train").shuffle()

Fourth, you need to init the `argilla` client with your Space URL and API key and upload the records into Argilla:

    import argilla as rg
    from datasets import load_dataset

    # You can find your Space URL behind the Embed this space button
    rg.init(
        api_url="<https://your-direct-space-url.hf.space>",
        api_key="admin.apikey" # this is the real API key default value
    )

    banking_ds = load_dataset("argilla/banking_sentiment_setfit", split="train")

    # Argilla expects labels in the annotation column
    # We include labels for demo purposes
    banking_ds = banking_ds.rename_column("label", "annotation")

    # Build argilla dataset from datasets
    argilla_ds = rg.read_datasets(banking_ds, task="TextClassification")

    # Create dataset
    rg.log(argilla_ds, "bankingapp_sentiment")

Congrats! Your dataset is available in the Argilla UI for data labeling. Once you have labelled some data, you can train your first model by reading the dataset using Python.

##
How to train a model with labelled data

In this example, we use SetFit, but you can use any other model for training.

To train a model using your labeled data, you need to read the labelled dataset and prepare it for training:

    # this will read the dataset and turn it into a clean dataset for training
    dataset = rg.load("bankingapp_sentiment").prepare_for_training()

To train a SetFit model with this dataset:

    from sentence_transformers.losses import CosineSimilarityLoss

    from setfit import SetFitModel, SetFitTrainer

    # Create train test split
    dataset = dataset.train_test_split()

    # Load SetFit model from Hub
    model = SetFitModel.from_pretrained("sentence-transformers/paraphrase-mpnet-base-v2")

    # Create trainer
    trainer = SetFitTrainer(
        model=model,
        train_dataset=dataset["train"],
        eval_dataset=dataset["test"],
        loss_class=CosineSimilarityLoss,
        batch_size=8,
        num_iterations=20,
    )

    # Train and evaluate
    trainer.train()
    metrics = trainer.evaluate()

Optionally, you can push the dataset to the Hub for later use:

    # save full argilla dataset for reproducibility
    rg.load("bankingapp_sentiment").to_datasets().push_to_hub("bankingapp_sentiment")

As a next step, check out the Argilla Tutorials section. All the tutorials can be run using Colab or local Jupyter Notebooks.
