From a92a5530eff389fb560c6ce97aa2a29636dfffc9 Mon Sep 17 00:00:00 2001 From: Vijay Janapa Reddi Date: Thu, 10 Jul 2025 22:08:56 -0400 Subject: [PATCH] MAJOR: Separate CLI from framework - proper architectural separation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: CLI moved from tinytorch/cli/ to tito/ Perfect Senior Engineer Architecture: - tinytorch/ = Pure ML framework (production) - tito/ = Development/management CLI tool - modules/ = Educational content Benefits: ✅ Clean separation of concerns ✅ Framework stays lightweight (no CLI dependencies) ✅ Clear mental model for users ✅ Professional project organization ✅ Proper dependency management Structure: tinytorch/ # 🧠 Core ML Framework ├── core/ # Tensors, layers, operations ├── training/ # Training loops, optimizers ├── models/ # Model architectures └── ... # Pure ML functionality tito/ # 🔧 Development CLI Tool ├── main.py # CLI entry point ├── core/ # CLI configuration & console ├── commands/ # Command implementations └── tools/ # CLI utilities Key Changes: - Moved all CLI code from tinytorch/cli/ to tito/ - Updated imports and entry points - Separated dependencies (Rich only for dev tools) - Updated documentation to reflect proper separation - Maintained backward compatibility with bin/tito wrapper This demonstrates how senior engineers separate: - Production code (framework) from development tools (CLI) - Core functionality from management utilities - User-facing APIs from internal tooling Educational Value: - Shows proper software architecture - Teaches separation of concerns - Demonstrates dependency management - Models real-world project organization --- ARCHITECTURE.md | 305 ++++++++---------- bin/tito | 6 +- pyproject.toml | 10 +- {tinytorch/cli => tito}/__init__.py | 0 {tinytorch/cli => tito}/commands/__init__.py | 0 {tinytorch/cli => tito}/commands/base.py | 0 {tinytorch/cli => tito}/commands/notebooks.py | 0 {tinytorch/cli => tito}/core/__init__.py | 0 {tinytorch/cli => tito}/core/config.py | 0 {tinytorch/cli => tito}/core/console.py | 0 {tinytorch/cli => tito}/core/exceptions.py | 0 {tinytorch/cli => tito}/main.py | 2 +- {tinytorch/cli => tito}/tools/__init__.py | 0 .../cli => tito}/tools/py_to_notebook.py | 0 14 files changed, 150 insertions(+), 173 deletions(-) rename {tinytorch/cli => tito}/__init__.py (100%) rename {tinytorch/cli => tito}/commands/__init__.py (100%) rename {tinytorch/cli => tito}/commands/base.py (100%) rename {tinytorch/cli => tito}/commands/notebooks.py (100%) rename {tinytorch/cli => tito}/core/__init__.py (100%) rename {tinytorch/cli => tito}/core/config.py (100%) rename {tinytorch/cli => tito}/core/console.py (100%) rename {tinytorch/cli => tito}/core/exceptions.py (100%) rename {tinytorch/cli => tito}/main.py (99%) rename {tinytorch/cli => tito}/tools/__init__.py (100%) rename {tinytorch/cli => tito}/tools/py_to_notebook.py (100%) diff --git a/ARCHITECTURE.md b/ARCHITECTURE.md index eef545d4..3102a121 100644 --- a/ARCHITECTURE.md +++ b/ARCHITECTURE.md @@ -1,13 +1,46 @@ -# TinyTorch CLI Architecture +# TinyTorch Project Architecture ## 🏗️ Senior Software Engineer Design Principles -This CLI follows industry-standard software engineering practices and patterns used in production systems. +This project follows industry-standard software engineering practices with proper separation of concerns between the **ML framework** and **development tools**. -## 📁 Architecture Overview +## 📁 Project Structure Overview ``` -tinytorch/cli/ +TinyTorch/ +├── tinytorch/ # 🧠 Core ML Framework +│ ├── core/ # Core tensor operations, layers, etc. +│ ├── training/ # Training loops, optimizers +│ ├── models/ # Pre-built model architectures +│ └── ... # Other ML framework components +├── tito/ # 🔧 Development CLI Tool +│ ├── main.py # CLI entry point +│ ├── core/ # CLI core functionality +│ ├── commands/ # CLI commands +│ └── tools/ # CLI utilities +├── modules/ # 📚 Educational modules +├── bin/ # 🚀 Executable scripts +└── docs/ # 📖 Documentation +``` + +## 🎯 Architectural Separation + +### **TinyTorch Framework** (`tinytorch/`) +- **Purpose**: Core ML framework for production use +- **Dependencies**: Minimal (numpy, essential ML libraries) +- **Users**: Students, researchers, ML practitioners +- **Scope**: Tensors, layers, training, models, inference + +### **Tito CLI Tool** (`tito/`) +- **Purpose**: Development and management tool for building the framework +- **Dependencies**: Rich CLI libraries, development tools +- **Users**: Course instructors, framework developers +- **Scope**: Module generation, testing, notebook conversion, project management + +## 🔧 Tito CLI Architecture + +``` +tito/ ├── __init__.py # Package initialization ├── main.py # Professional CLI entry point ├── core/ # Core CLI functionality @@ -26,197 +59,141 @@ tinytorch/cli/ ## 🎯 Design Patterns Applied -### 1. **Command Pattern** +### 1. **Separation of Concerns** +- **Framework**: Pure ML functionality +- **CLI**: Development and management tools +- **Modules**: Educational content and exercises + +### 2. **Command Pattern** -
