# Tabular
|
|
|
|
|
|
|
|
|
|
The Tabular pipeline splits tabular data into rows and columns. The tabular pipeline is most useful in creating (id, text, tag) tuples to load into Embedding indexes.
|
|
|
|
## Example
|
|
|
|
The following shows a simple example using this pipeline.
|
|
|
|
```python
|
|
from txtai.pipeline import Tabular
|
|
|
|
# Create and run pipeline
|
|
tabular = Tabular("id", ["text"])
|
|
tabular("path to csv file")
|
|
```
|
|
|
|
See the link below for a more detailed example.

## Configuration-driven example
|
|
|
|
Pipelines are run with Python or configuration. Pipelines can be instantiated in [configuration](../../../api/configuration/#pipeline) using the lower case name of the pipeline. Configuration-driven pipelines are run with [workflows](../../../workflow/#configuration-driven-example) or the [API](../../../api#local-instance).
|
|
|
|
### config.yml
|
|
```yaml
|
|
# Create pipeline using lower case class name
|
|
tabular:
|
|
idcolumn: id
|
|
textcolumns:
|
|
- text
|
|
|
|
# Run pipeline with workflow
|
|
workflow:
|
|
tabular:
|
|
tasks:
|
|
- action: tabular
|
|
```
|
|
|
|
### Run with Workflows
|
|
|
|
```python
|
|
from txtai import Application
|
|
|
|
# Create and run pipeline with workflow
|
|
app = Application("config.yml")
|
|
list(app.workflow("tabular", ["path to csv file"]))
|
|
```
|
|
|
|
### Run with API
|
|
|
|
```bash
|
|
CONFIG=config.yml uvicorn "txtai.api:app" &
|
|
|
|
curl \
|
|
-X POST "http://localhost:8000/workflow" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"name":"tabular", "elements":["path to csv file"]}'
|
|
```
|
|
|
