dv-core-asta 0.2.0

DataVoyager Core with Asta Integration - AI agent for data analysis

This is the asta-flavor of DataVoyager. The standalone and original DataVoyager is datavoyager-core. Documentation there may still be relevant for unchanged parts of the core.

Development Setup

If you only need to work on the agent itself (this repo) without use of the Asta webapp or ecosystem, follow this guide. For e2e development of DV-Asta integration, see https://github.com/allenai/nora/wiki/DataVoyager-development which details all the processes you need control of.

This project uses uv for dependency management and assumes python 3.12. Install uv, then

uv sync

Go to 1password and get "datavoyager agent secrets." You will need to export these vars to your environment. If you use something like direnv, you can put those exports directly in your .envrc file. Don't forget to direnv allow.

Make a copy of .env.template to .env. If the secrets are exported to your environment then no further changes are needed. Otherwise, to get those secrets into docker containers, edit .env with all the secret values.

Check that you can start the agent in local mode. You should see something like this.

$> uv run python local.py
* config_file=config/datavoyager_modal_deployment_magentic_one_config_20250617.yaml
* json_logger.log_filename=threads/local-2025-08-05T10-28-36.981698/log.jsonl
* md_logger.log_filename=threads/local-2025-08-05T10-28-36.981698/log.md
* asta_logs.log_file=threads/local-2025-08-05T10-28-36.981698/log.istore.json
* console_log=threads/local-2025-08-05T10-28-36.981698/console.log

Here you can interact with the agent like you would in the Asta webapp. A number of Asta integrations have been swapped with plaintext versions. DataVoyager's reasoning will spray into the console. As it happens you will be able to see evidence of various Asta-specific features, though rendered as plaintext. A few are called out in the excerpts from an example run below.

Here I pasted one of the stock queries from https://datavoyager.allen.ai into the terminal.

Out of age and gender, which factor affects the survival of titanic passengers the most? Use 
the following dataset.

• s3://ai2-asta-workspaces/sampledata/titanic.csv


-----------------------------------------------------------------------------------------------

Step progress events have a unique treatment in the Asta UX, though they are simply mentioned in plaintext here.

>>> entering step >>> Checking for datasets
<<< exited step <<< Loaded 1 new dataset(s)
>>> entering step >>> Pre-processing request
<<< exited step <<< Pre-processing request
>>> entering step >>> Investigating

<dvtext> marks spans that will not be forwarded to the Asta UX, but is important to DV's internal reasoning.

We are working to address the following REQUEST:

Question: Out of age and gender, which factor affects the survival of titanic passengers the 
most? Use the following dataset.

• s3://ai2-asta-workspaces/sampledata/titanic.csv

Python variable name for dataset: data_0
Dataset preview:
Dataset head:
PassengerId  Survived  Pclass  ...     Fare Cabin  Embarked
0            1         0       3  ...   7.2500   NaN         S
1            2         1       1  ...  71.2833   C85         C
2            3         1       3  ...   7.9250   NaN         S

Eventually the agent will finish with what we consider the answer to the user query which is annotated with <dvoutput>. The Asta UX picks up these tags to power specific UX behaviors.

<<< exited step <<< Investigation complete.

Asta: <dvoutput cell_id="10">
Based on the analysis of the Titanic dataset, the factor that has the most significant impact 
on passenger survival is gender. The logistic regression results indicate that being female, 
compared to being male, increases the odds of survival by approximately 1124.74%. In contrast, 
age has a negligible effect on the odds of survival, with the regression suggesting only a 
minor change of -0.47% per additional year. Thus, gender is the more impactful factor affecting
survival rates among Titanic passengers.

Deployment

Make sure you have set up the necessary secrets in your environment, as described above. Set up the .env file so that underlying docker containers will have those secrets.

The modal app name is figured as f"dv-core.{ENV}". Here is the modal.com dashboard with all existing environments. The dv-core.rc environment is automatically updated with the code in the main branch via a github action, so long as they pass tests. Other environments must be updated manually. For example, to deploy to my own personal development deployment called dv-core.jasond

ENV=jasond make deploy

The prod modal environment dv-core.prod is the last stable version of this codebase and is depended upon by the asta.allen.ai asta environment for code stability. When it is time to release this codebase's main to the prod modal environment, run whatever automated and manual tests needed to gain confidence that the current version of code is good before deploying it. To deploy to the prod modal environment you can run the deploy command above locally (changing the ENV value), or you can use the deploy-prod github workflow (under the actions tab). The latter is preferred. Please note: your changes will not be reflected in the asta.allen.ai environment, unless your changes are in the prod modal environment.

PyPI Installation and Publishing

DV can be run as a standalone CLI, installed from pypi:

uv pip install dv-core-asta
dv --help

To cut a new release:

1. Bump the version:

• On your PR branch:
• make show-version
• make set-version VERSION=x.y.z

2. Just before merging to main:

• make push-version-tag

3. On GitHub, in the Actions tab, run the Publish to PyPI workflow

• Enter the version tag (e.g., v1.1.7) as the version input

Logs

Logs from the main DV process in modal are forwarded to GCP to the ai2-reviz project. They can be correlated with other activity there. See https://github.com/allenai/nora/wiki/Log-Filtering-and-Navigation

Remote File Sharing

Remote executions (Docker or Modal) use a shared FileShareSpec abstraction to declare which paths should exist inside the runtime. See docs/remote_file_sharing.md for the full guide.
