DeepCode - Issues Fixed ✓

Problems Resolved

1. 404 Errors - Connection Handling ✓

Issue: Agent returned generic "Error: 404" without context Fix:

  • Added detailed error messages for connection problems
  • Implemented _check_connection() method to verify Ollama is accessible
  • Proper HTTP status code handling (404, 500, timeouts)

2. Unclear Error Messages ✓

Issue: User couldn't understand why agent failed Fix:

  • Specific error messages for each failure type
  • Built-in troubleshooting tips
  • Suggests exact commands to fix issues

3. Missing Model Guidance ✓

Issue: "Model not found" without help on what to do Fix:

  • Shows which models are available
  • Suggests ollama pull commands
  • Links to API endpoint for verification

4. Silent Failures ✓

Issue: Agent would hang or fail silently Fix:

  • Better timeout handling (distinguishes between slow response and timeout)
  • Connection errors are caught and reported
  • Fallback messages for all error scenarios

Code Changes Made

File: deepcode.py

  1. Added _check_connection() method

    • Verifies Ollama is running before tasks
    • Provides immediate feedback on startup

  2. Improved _check_models() method

    • Better error handling for connection failures
    • Distinguishes between connection error and 404

  3. Enhanced call_llm() method

    • Handles specific HTTP status codes (404, 500)
    • Connection error handling
    • Timeout detection with clear messages

  4. Better _call_agent() method

    • Same improvements for multi-agent mode

  5. Improved main loop in process_task()

    • Detects error responses
    • Shows troubleshooting tips
    • Gracefully exits on connection errors

Before vs After

Before

Error: 404
✨ Task Complete!

❌ User confused - what went wrong? How to fix?

After

Error: Model 'qwen2.5-coder:latest' not found on Ollama. 
Available at http://localhost:11434/api/tags        

💡 Troubleshooting tips:
  1. Make sure Ollama is running: 'ollama serve'
  2. Check if model is installed: 'ollama list'
  3. Pull the model: 'ollama pull qwen2.5-coder'

✅ User knows exactly what to do

How to Use the Fixes

Quick Start (Windows)

# Terminal 1: Start Ollama
ollama serve

# Terminal 2: Run DeepCode
python deepcode.py

If You Get 404 Errors

The script now automatically detects and suggests:

  1. Check Ollama is running
  2. Install missing models
  3. Verify connection

Features

  • ✓ Real-time connection checking
  • ✓ Helpful error messages
  • ✓ Auto-troubleshooting suggestions
  • ✓ Clear model availability info
  • ✓ Timeout detection

Testing the Fixes

The code has been tested with:

  • ✓ Ollama running (connection success)
  • ✓ Ollama offline (connection failure detected)
  • ✓ Models missing (helpful suggestions)
  • ✓ Invalid model names (clear error)

Next Steps

  1. Start Ollama: ollama serve
  2. Install models: 
    ollama pull qwen2.5-coder
ollama pull deepseek-coder-v2:16b
  3. Run DeepCode: python deepcode.py
  4. Try a task: build a rest api
