Best Practices
- Start Small: Begin with
nanoorminitiers for experimentation - Use Templates: Leverage marketplace templates for common tasks
- Monitor Training: Check status regularly to catch issues early
- Benchmark Models: Always benchmark before production deployment
- Distributed Training: Use clusters for large models (>1B parameters)
- Federated Learning: Use for privacy-sensitive data
- Version Models: Publish successful models as templates for reuse
- Validate Thoroughly: Use validation workflows before deployment
Troubleshooting
Training Stalled
```javascript
// Check cluster status
const status = await mcp__flow-nexus__neural_cluster_status({
cluster_id: "cluster_id"
})
// Terminate and restart if needed
await mcp__flow-nexus__neural_cluster_terminate({
cluster_id: "cluster_id"
})
```
Low Accuracy
- Increase epochs
- Adjust learning rate
- Add regularization (dropout)
- Try different optimizer
- Use data augmentation
Out of Memory
- Reduce batch size
- Use smaller model tier
- Enable gradient accumulation
- Use distributed training
