Practical overview
When it fits
Use Ryoma when building a Python-based data agent, especially when a workflow should connect a language model to a database or when a Reflex-based local interface is useful.
Who it is for
- Python developers building AI-assisted data workflows.
- Data practitioners who want to query a PostgreSQL database through a language-model agent.
- Teams exploring a local web interface for interacting with data and AI models.
Documented uses
- Build a data-analysis agent to explore and interpret datasets.
- Create an agent that assists with data engineering tasks.
- Develop an agent for data visualization.
- Ask a database question in natural language and have an agent prepare and run a SQL query.
Requirements & limits
Ryoma is published under the Apache-2.0 license. The documented installation uses pip.
- The README's concrete agent example uses PostgreSQL and demonstrates a tool call that executes SQL.
- Model-provider support requires the corresponding Python packages and, for providers that use credentials, the relevant environment variables.
- The project lists LangChain, Reflex, Apache Arrow, Jupyter AI Magics, Amundsen, Ibis and Feast in its stack.
- The package is installed as
ryoma_ai; the optional Snowflake extra is documented asryoma_ai[snowflake].
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up Ryoma Lab
Configure and start the Reflex-based Ryoma Lab interface locally.
Before you start
- Install the Ryoma package and its dependencies in a Python project.
- Create an rxconfig.py file in the project.
Steps
Add the documented Reflex configuration to rxconfig.py, setting the app name to ryoma_lab and the log level to INFO.
Run
ryoma_lab runfrom the project.Open the local interface at
http://localhost:3000.
Expected outcome
Ryoma Lab is available through a local web interface.
Guide limitations
- The documented steps describe starting the interface, not connecting a specific data source or model inside it.
