# Streamlit
|
|
|
|
[Streamlit](https://github.com/streamlit/streamlit) lets you transform Python scripts into interactive web apps in minutes, instead of weeks. Build dashboards, generate reports, or create chat apps.
|
|
|
|
It can be quickly integrated with vLLM as a backend API server, enabling powerful LLM inference via API calls.
|
|
|
|
## Prerequisites
|
|
|
|
Set up the vLLM environment by installing all required packages:
|
|
|
|
```bash
|
|
pip install vllm streamlit openai
|
|
```
|
|
|
|
## Deploy
|
|
|
|
1. Start the vLLM server with a supported chat completion model, e.g.
|
|
|
|
```bash
|
|
vllm serve Qwen/Qwen1.5-0.5B-Chat
|
|
```
|
|
|
|
1. Use the script: <gh-file:examples/online_serving/streamlit_openai_chatbot_webserver.py>
|
|
|
|
1. Start the streamlit web UI and start to chat:
|
|
|
|
```bash
|
|
streamlit run streamlit_openai_chatbot_webserver.py
|
|
|
|
# or specify the VLLM_API_BASE or VLLM_API_KEY
|
|
VLLM_API_BASE="http://vllm-server-host:vllm-server-port/v1" \
|
|
streamlit run streamlit_openai_chatbot_webserver.py
|
|
|
|
# start with debug mode to view more details
|
|
streamlit run streamlit_openai_chatbot_webserver.py --logger.level=debug
|
|
```
