| ## h2oGPT integration with LangChain and SerpAPI | |
| Web search augments LLM context with additional information obtained from duck duck go (can be changed in code) search results. | |
| * Install search package | |
| ```bash | |
| pip install -r reqs_optional/requirements_optional_agents.txt | |
| ```` | |
| * Setup account at https://serpapi.com/ (they have some number of free searches for free accounts) | |
| * Setup ENV that defines: `SERPAPI_API_KEY` | |
| * Start h2oGPT as normal | |
| * You should see web search available in `Resources` | |
| * Additionally, the SEARCH agent will appear in `Resources` under `Agents`. These agents are highly experimental and works best with OpenAI at moment. | |
| ## Issues | |
| When web search is enabled, it has been seen that eventually it leads to some closing of sys.stdout and one gets these errors: | |
| ``` | |
| ValueError: I/O operation on closed file. | |
| ``` | |
