Telco Troubleshooting Agentic Challenge

Overview

World-class implementation of a ReAct (Reasoning and Acting) agent for the Telco Troubleshooting Agentic Challenge, featuring:

• 4-bit quantized Qwen2.5-35B with multi-GPU sharding for Kaggle T4x2
• QLoRA fine-tuning for telecom-specific tool usage
• ReAct agent loop with Thought → Action → Action Input structure
• Phase 2/3 compliance with full trace logging
• Sub-5 minute execution for Phase 3 time constraints

Phase 1: Foundation & Baseline

Prerequisites

• Kaggle T4x2 (32GB total VRAM) - REQUIRED for 35B model
• Python 3.8+ with CUDA support
• Hugging Face token with model access

Installation

# Clone repository
git clone <repository-url>
cd telco-troubleshooting-agentic-challenge

# Install dependencies
pip install -r requirements.txt

# Set Hugging Face token (if needed)
export HF_TOKEN="your_hf_token_here"

Quick Start

# Test 4-bit model loading
python -c "from agent.llm_engine import get_llm_engine; engine = get_llm_engine(); print('Model loaded!')"

# Run agent test
python main.py --test

Generate First Submission

# Generate baseline submission
python main.py --scenarios data/test_scenarios.json --output result.csv

# Submit to Zindi leaderboard
# Upload result.csv to: https://zindi.africa/competitions/telco-troubleshooting-agentic-challenge/submit

Phase 2: QLoRA Fine-Tuning

Data Preparation

# Convert traces.json to SFT format
python data_prep/trace_to_sft.py --traces data/raw/traces.json --output data/sft_training_data.json

# Analyze training data
python data_prep/trace_to_sft.py --analyze

Training on Kaggle T4x2

1. Upload to Kaggle:

   • Upload project to Kaggle
   • Ensure notebooks/01_qlora_train.ipynb is included

2. Run Training:

   • Open 01_qlora_train.ipynb in Kaggle
   • Select T4x2 GPU accelerator
   • Run all cells

3. Training Config:

   • 4-bit NF4 quantization
   • QLoRA adapters (r=16, alpha=32)
   • 3 epochs, effective batch size 8
   • Target modules: q_proj, v_proj, k_proj, o_proj, gate_proj, up_proj, down_proj

Expected Training Metrics

• Memory usage: ~28GB on T4x2
• Training time: ~2-3 hours for 3 epochs
• Parameters: ~0.5% trainable (LoRA only)

Phase 3: Latency Optimization

Inference Setup

# Run full agent with trained adapters
python main.py \
    --server http://localhost:8000 \
    --scenarios data/phase3_scenarios.json \
    --output result.csv \
    --traces traces.json

Performance Targets

• Execution time: < 5 minutes (100% score)
• Memory usage: < 30GB VRAM
• Success rate: > 80% tool execution

Optimization Techniques

1. Aggressive token limits: max_new_tokens=256
2. Prompt pruning: Limit conversation history
3. Caching: Cache tool results
4. Batch processing: Process multiple scenarios

Development Guide

Local Testing

# Test individual components
python -m agent.llm_engine
python -m agent.react_loop
python -m agent.tools
python -m agent.trace_logger

# Test full agent
python main.py --scenario data/test_scenario.json

Server Setup

# Start telco server (mock for testing)
python server.py --port 8000

# Or use ngrok for remote access
ngrok http 8000

Trace Analysis

# Validate trace format
python main.py --validate --traces traces.json

# Analyze execution patterns
python -c "import json; traces=json.load(open('traces.json')); print(f'Total traces: {len(traces)}')"

Troubleshooting

Common Issues

1. OOM Error:

   • Reduce max_seq_length to 1024
   • Use smaller batch size
   • Ensure 4-bit quantization

2. Slow Inference:

   • Check GPU memory usage
   • Reduce max_new_tokens
   • Enable use_cache=True

3. Tool Failures:

   • Verify server URL
   • Check network connectivity
   • Review tool parameters

Debug Mode

# Enable verbose logging
export LOGGING_LEVEL=DEBUG

# Run with debug traces
python main.py --debug --traces debug_traces.json

Competition Strategy

Track Selection

• Track A (IoU): Recommended - partial credit, structured APIs
• Track B (Exact Match): Harder - unforgiving but smaller question pool

Winning Factors

1. Speed: Sub-5 minute execution for Phase 3
2. Accuracy: High tool execution success rate
3. Robustness: Error recovery and retry logic
4. Compliance: Proper trace logging format

Expected Leaderboard Position

• Phase 1: Top 20% (baseline)
• Phase 2: Top 10% (with QLoRA)
• Phase 3: Top 1% (with optimization)
