"""
Example showing how to chat with a tabular dataset:
csv, tsv, or any other pandas-readable.

Run like this

python3 examples/data-qa/table_chat.py

Optional args:
* -d or --debug to enable debug mode
* -ns or --nostream to disable streaming
* -nc or --nocache to disable caching
* -m or --model to specify a model name

To run with a local model via ollama, do this:
```
ollama run dolphin-mixtral # best model for this script

python3 examples/data-qa/table_chat.py -m ollama/dolphin-mixtral:latest
```

For more info on running Langroid with local LLM, see here:
