## 🎉 Tóm Tắt Hoàn Thành
Tôi đã tạo xong một **workflow hoàn chỉnh** cho bạn, giải quyết vấn đề:
> "Tôi phải code trên máy cá nhân, sau đó up lên server chạy. Điều đó bất tiện vô cùng vì data để train chỉ có trên server."
---
## ✨ Giải Pháp
### **Workflow 3 Bước:**
1. **Server** (1-3 giờ): Tải S3 → Xử lý → Lưu NetCDF
2. **Local** (30 min - 2 giờ): Load data → Train CNN
3. **Local** (10-30 phút): Predict → Lưu kết quả
**Lợi ích**:
- ✅ Code trên máy local (không cần up server)
- ✅ Kéo data nhỏ (~300MB thay vì 10GB)
- ✅ Train nhanh trên GPU local
- ✅ Không chiếm resource server
