Streamlit Testing App - Setup Guide

Installation

pip install streamlit gradio_client

Running Locally

cd plate-detector
streamlit run streamlit_app.py

Fixing API Errors

If you see errors like:

❌ Cannot find a function with `api_name`: /detect
❌ Cannot find a function with `api_name`: /run_query

Step 1: Find Correct API Names

1. Open the sidebar and click "Show Available APIs" button
2. This will display all available API endpoints from your Space
3. Look for the correct function names

Step 2: Update API Names

Edit streamlit_app.py and update these lines:

API_NAME_DETECT = "/predict"      # Change this to actual API name
API_NAME_QUERY = "/predict_1"     # Change this to actual API name

Common patterns:

• First function: /predict
• Second function: /predict_1
• Or numbered: /predict_0, /predict_1, etc.

Step 3: Test Again

streamlit run streamlit_app.py

Features

✅ Detection Tab - Upload image and detect license plate ✅ Query Tab - Natural language database queries ✅ Analytics Tab - View statistics and trends ✅ API Debugging - Shows available endpoints and errors

Troubleshooting

Issue	Solution
use_column_width deprecated	✅ Fixed - already updated to use_container_width
API not found	Click "Show Available APIs" in sidebar to see correct names
Connection failed	Make sure Space URL is correct: BARATH0070/plate-detector
No results	Check if HF_TOKEN and DATABASE_URL are set in your Space

Notes

• This is a LOCAL testing app only
• Do NOT push to HF Spaces
• Use it to test UI/UX before deploying
• Make sure your Gradio Space is running and accessible
