accelerate launch -m axolotl.cli.train examples/swanlab/dpo-swanlab-full-featured.yml

4. Custom Trainer Profiling (Python)

File: custom_trainer_profiling.py

Python code examples showing how to add SwanLab profiling to custom trainers.

Features:

  • @swanlab_profile decorator examples
  • Context manager profiling for fine-grained timing
  • ProfilingConfig for advanced filtering and throttling
  • Multiple profiling patterns and best practices

Best for: Advanced users creating custom trainers

Usage:

from custom_trainer_profiling import CustomTrainerWithProfiling
# See file for detailed examples and patterns

Configuration Quick Reference

Basic SwanLab Setup

plugins:
  - axolotl.integrations.swanlab.SwanLabPlugin

use_swanlab: true
swanlab_project: my-project
swanlab_experiment_name: my-experiment
swanlab_mode: cloud  # cloud, local, offline, disabled

RLHF Completion Logging

swanlab_log_completions: true
swanlab_completion_log_interval: 100  # Log every 100 steps
swanlab_completion_max_buffer: 128    # Memory-bounded buffer

Lark Team Notifications

swanlab_lark_webhook_url: https://open.feishu.cn/...
swanlab_lark_secret: your-webhook-secret  # Required for production

Team Workspace

swanlab_workspace: my-research-team

Private Deployment

swanlab_web_host: https://swanlab.yourcompany.com
swanlab_api_host: https://api.swanlab.yourcompany.com

Authentication

export SWANLAB_API_KEY=your-api-key
export SWANLAB_LARK_WEBHOOK_URL=https://open.feishu.cn/...
export SWANLAB_LARK_SECRET=your-webhook-secret

Alternative: Config File (less secure)

swanlab_api_key: your-api-key
swanlab_lark_webhook_url: https://open.feishu.cn/...
swanlab_lark_secret: your-webhook-secret

Common Use Cases

Use Case 1: Migrate from WandB to SwanLab

Start with lora-swanlab-profiling.yml, add your model/dataset config, disable WandB:

use_swanlab: true
use_wandb: false

Use Case 2: Analyze DPO Model Outputs

Use dpo-swanlab-completions.yml, adjust completion logging interval based on your training length:

swanlab_completion_log_interval: 50   # More frequent for short training
swanlab_completion_log_interval: 200  # Less frequent for long training

Use Case 3: Optimize Training Performance

Use lora-swanlab-profiling.yml, run multiple experiments with different optimizations:

  • Baseline: flash_attention: false, gradient_checkpointing: false
  • Flash Attention: flash_attention: true
  • Gradient Checkpointing: gradient_checkpointing: true
  • Both: flash_attention: true, gradient_checkpointing: true

Compare profiling metrics in SwanLab dashboard.

Use Case 4: Production RLHF with Team Collaboration

Use dpo-swanlab-full-featured.yml, set up team workspace and Lark notifications:

swanlab_workspace: ml-team
swanlab_lark_webhook_url: ...
swanlab_lark_secret: ...

Viewing Your Experiments

Cloud Mode

Visit https://swanlab.cn and navigate to your project.

Dashboard sections:

  • Metrics: Training loss, learning rate, profiling metrics
  • Tables: RLHF completions (for DPO/KTO/ORPO/GRPO)
  • Config: Hyperparameters and configuration
  • System: Resource usage (GPU, memory, CPU)
  • Files: Logged artifacts

Local Mode

swanlab watch ./swanlog
# Open browser to http://localhost:5092

Troubleshooting

SwanLab not initializing

# Check API key
echo $SWANLAB_API_KEY

# Verify SwanLab is installed
pip show swanlab

# Check config
grep -A 5 "use_swanlab" your-config.yml

Completions not appearing

  • Verify you're using an RLHF trainer (DPO/KTO/ORPO/GRPO)
  • Check swanlab_log_completions: true
  • Wait for swanlab_completion_log_interval steps
  • Look for "Registered SwanLab RLHF completion logging" in logs

Lark notifications not working

  • Test webhook manually: curl -X POST "$SWANLAB_LARK_WEBHOOK_URL" ...
  • Verify SWANLAB_LARK_SECRET is set correctly
  • Check bot is added to Lark group chat
  • Look for "Registered Lark notification callback" in logs

Profiling metrics not appearing

  • Verify use_swanlab: true
  • Check SwanLab is initialized (look for init log message)
  • Profiling metrics are under "profiling/" namespace
  • Profiling auto-enabled when SwanLab is enabled

Performance Notes

Overhead Comparison

Feature Overhead per Step Memory Usage
Basic tracking < 0.1% ~10 MB
Completion logging < 0.5% ~64 KB (buffer=128)
Profiling < 0.1% ~1 KB
Total < 0.7% ~10 MB

Best Practices

  1. Use ONE logging tool in production (disable WandB/MLflow when using SwanLab)
  2. Adjust completion log interval based on training length (100-200 steps)
  3. Keep completion buffer size reasonable (128-512)
  4. Profile critical path methods first (training_step, compute_loss)
  5. Use ProfilingConfig to throttle high-frequency operations
