# TinyTorch + nbgrader Integration Proposal
## Executive Summary
This proposal outlines how to integrate **nbgrader** with TinyTorch to create a comprehensive course management system that supports both **self-paced learning** and **formal assessment** from the same source materials.
## The Problem
Current TinyTorch has excellent educational content but lacks:
- **Automated grading** for large courses
- **Formal assessment** workflow
- **Immediate feedback** for student implementations
- **Grade tracking** and LMS integration
- **Scalable evaluation** for hundreds of students
## The Solution: Dual-Purpose Content
### Current System (Enhanced)
```python
class Tensor:
def __init__(self, data):
"""Create tensor from data"""
#| exercise_start # TinyTorch marker
#| hint: Use np.array() to convert data
#| difficulty: easy
### BEGIN SOLUTION # nbgrader marker
self._data = np.array(data)
### END SOLUTION
#| exercise_end
### BEGIN HIDDEN TESTS # nbgrader auto-grading
def test_init():
t = Tensor([1, 2, 3])
assert t._data.tolist() == [1, 2, 3]
### END HIDDEN TESTS
```
### Generates Two Student Versions
#### 1. Self-Learning Version (Current TinyTorch Style)
```python
class Tensor:
def __init__(self, data):
"""Create tensor from data"""
# 🟡 TODO: Implement tensor creation (easy)
# HINT: Use np.array() to convert data
# Your implementation here
pass
```
#### 2. Assignment Version (nbgrader Compatible)
```python
class Tensor:
def __init__(self, data):
"""Create tensor from data"""
### BEGIN SOLUTION
# YOUR CODE HERE
raise NotImplementedError()
### END SOLUTION
### BEGIN HIDDEN TESTS
def test_init():
t = Tensor([1, 2, 3])
assert t._data.tolist() == [1, 2, 3]
### END HIDDEN TESTS
```
## Implementation Strategy
### Phase 1: Enhanced Marking System ✅
- [x] Add nbgrader markers to existing framework

## Conclusion
The TinyTorch + nbgrader integration represents a **paradigm shift** from traditional course management to an **intelligent, scalable educational system** that:
1. **Preserves TinyTorch's pedagogical philosophy** while adding assessment capabilities
2. **Scales to large courses** without sacrificing educational quality
3. **Provides flexibility** for different learning styles and course structures
4. **Maintains single-source truth** for all educational materials
5. **Enables data-driven improvement** through comprehensive analytics
This system transforms TinyTorch from a learning framework into a **complete course management solution** that can handle everything from individual self-study to large-scale university courses.
### Next Steps
1. **Review and approve** this proposal
2. **Implement Phase 2** (nbgrader integration)
3. **Pilot with one module** (tensor recommended)
4. **Gather feedback** and iterate
5. **Scale to full course** deployment
The enhanced system is ready for immediate implementation and testing. The dual generation capability is already working, and the nbgrader integration requires only standard nbgrader setup and configuration.

# NBGrader Integration Guide
This guide explains how TinyTorch integrates with nbgrader for enhanced assignment management and auto-grading.
## Overview
TinyTorch supports **three levels of student interaction**:
1. **🎓 Self-Learning**: Regular student notebooks with rich educational content
2. **📝 Assignments**: nbgrader-compatible assignments with auto-grading
3. **🔧 Production**: Working package with instructor solutions
## Architecture
### Instructor Development Flow
```mermaid
graph TD
A[Complete Implementation<br/>modules/tensor/tensor_dev.py] --> B[NBDev Export<br/>tinytorch/core/tensor.py]
A --> C[Student Notebook<br/>modules/tensor/tensor_student.ipynb]
A --> D[nbgrader Assignment<br/>modules/tensor/tensor_assignment.ipynb]
D --> E[Auto-grading<br/>Grade submissions]
C --> F[Self-paced Learning]
B --> G[Working Package]
```
### Dual Marking System
TinyTorch supports both marking systems simultaneously:
```python
# Enhanced module with both systems
class Tensor:
def __init__(self, data):
"""
Create a tensor from data.
Args:
data: Input data (scalar, list, or numpy array)
"""
#| exercise_start
#| hint: Use np.array() to convert input data
#| solution_test: tensor.shape should match input shape
#| difficulty: easy
### BEGIN SOLUTION
self._data = np.array(data)
### END SOLUTION
#| exercise_end
### BEGIN HIDDEN TESTS
def test_tensor_creation(self):
"""Hidden tests for auto-grading"""
t = Tensor([1, 2, 3])
assert t.shape == (3,)
assert isinstance(t.data, np.ndarray)
### END HIDDEN TESTS
```
## Usage
### Generate Student Notebooks (Self-Learning)
```bash
# Generate regular student notebooks
python bin/generate_student_notebooks.py --module tensor
# Result: modules/tensor/tensor_student.ipynb
# - Rich educational content
# - TODO placeholders with hints
# - Self-paced learning
```
### Generate nbgrader Assignments
```bash
# Generate nbgrader-compatible assignments
python bin/generate_student_notebooks.py --module tensor --nbgrader
# Result: modules/tensor/tensor_assignment.ipynb
# - nbgrader markers preserved
# - Auto-grading ready
# - Hidden tests included
```
### Batch Generation
```bash
# Generate all modules
python bin/generate_student_notebooks.py --all
python bin/generate_student_notebooks.py --all --nbgrader
```
## nbgrader Configuration
### Setup nbgrader Environment
```bash
# Install nbgrader
pip install nbgrader
# Initialize nbgrader in course directory
nbgrader quickstart course_name
# Configure nbgrader
jupyter nbextension install --sys-prefix --py nbgrader --overwrite
jupyter nbextension enable --sys-prefix --py nbgrader
jupyter serverextension enable --sys-prefix --py nbgrader
```
### Course Configuration
Create `nbgrader_config.py`:
```python
# nbgrader_config.py
c = get_config()
# Course settings
c.CourseDirectory.course_id = "ml-systems-tinytorch"
c.CourseDirectory.source_directory = "assignments"
c.CourseDirectory.release_directory = "release"
c.CourseDirectory.submitted_directory = "submitted"
c.CourseDirectory.autograded_directory = "autograded"
c.CourseDirectory.feedback_directory = "feedback"
# Auto-grading settings
c.Execute.timeout = 300 # 5 minutes per cell
c.Execute.allow_errors = True
c.Execute.error_on_timeout = True
# Feedback settings
c.ClearSolutions.code_stub = {
"python": "# YOUR CODE HERE\nraise NotImplementedError()"
}
```
## Assignment Workflow
### 1. Create Assignment
```bash
# Copy assignment notebook to nbgrader source
cp modules/tensor/tensor_assignment.ipynb assignments/tensor/tensor.ipynb
# Generate assignment
nbgrader generate_assignment tensor
# Release to students
nbgrader release_assignment tensor
```
### 2. Student Submission
Students work on assignments in the `release/tensor/` directory:
```python
# Students see this:
class Tensor:
def __init__(self, data):
### BEGIN SOLUTION
# YOUR CODE HERE
raise NotImplementedError()
### END SOLUTION
# Hidden tests run automatically
```
### 3. Auto-grading
```bash
# Collect submissions
nbgrader collect tensor
# Auto-grade submissions
nbgrader autograde tensor
# Generate feedback
nbgrader generate_feedback tensor
```
## Advanced Features
### 1. Partial Credit
```python
# In instructor version
class Tensor:
def multiply(self, other):
### BEGIN SOLUTION
# Full implementation (10 points)
result = self._data * other._data
return Tensor(result)
### END SOLUTION
### BEGIN HIDDEN TESTS
def test_multiply_basic():
"""Basic multiplication (5 points)"""
t1 = Tensor([1, 2, 3])
t2 = Tensor([2, 3, 4])
result = t1.multiply(t2)
assert result.data.tolist() == [2, 6, 12]
def test_multiply_advanced():
"""Advanced multiplication (5 points)"""
t1 = Tensor([[1, 2], [3, 4]])
t2 = Tensor([[2, 3], [4, 5]])
result = t1.multiply(t2)
assert result.shape == (2, 2)
### END HIDDEN TESTS
```
### 2. Progressive Difficulty
```python
# Easy exercise (auto-graded)
### BEGIN SOLUTION
def add_tensors(a, b):
return Tensor(a.data + b.data)
### END SOLUTION
# Medium exercise (auto-graded + manual review)
### BEGIN SOLUTION
def matrix_multiply(a, b):
# Implementation with error handling
if a.shape[1] != b.shape[0]:
raise ValueError("Incompatible shapes")
return Tensor(np.dot(a.data, b.data))
### END SOLUTION
# Hard exercise (manual grading)
"""
Design Question: Explain your tensor broadcasting strategy.
Discuss trade-offs between memory usage and computation speed.
"""
```
### 3. Integration with TinyTorch CLI
Extend the `tito` CLI to support nbgrader:
```bash
# Generate assignments
tito assignment --create tensor
# Grade submissions
tito assignment --grade tensor
# Release feedback
tito assignment --feedback tensor
```
## Benefits
### For Instructors
1. **Dual-purpose content**: Same source creates both learning and grading materials
2. **Auto-grading**: Reduces grading workload significantly
3. **Consistent evaluation**: Standardized testing across students
4. **Detailed feedback**: Automatic feedback generation
5. **Grade tracking**: Integration with LMS systems
### For Students
1. **Immediate feedback**: Know if implementation is correct
2. **Progressive learning**: Build on verified foundations
3. **Flexible learning**: Choose between self-paced or assignment modes
4. **Real testing**: Same tests used in production package
### For Course Management
1. **Scalability**: Handle large class sizes
2. **Consistency**: Same quality across all students
3. **Analytics**: Track student progress and common issues
4. **Reusability**: Assignments work across semesters
## Migration Strategy
### Phase 1: Enhanced Marking (Current)
- Add nbgrader markers to existing modules
- Enhance student notebook generator
- Test dual generation system
### Phase 2: nbgrader Integration
- Set up nbgrader environment
- Configure auto-grading workflows
- Train instructors on new system
### Phase 3: Full Deployment
- Deploy to production course
- Collect feedback and iterate
- Expand to all modules
## Best Practices
### 1. Test Design
```python
# Good: Specific, focused tests
def test_tensor_creation():
t = Tensor([1, 2, 3])
assert t.shape == (3,)
assert t.data.tolist() == [1, 2, 3]
# Good: Edge case testing
def test_tensor_empty():
t = Tensor([])
assert t.shape == (0,)
assert t.size == 0
```
### 2. Student Guidance
```python
# Good: Clear instructions
def forward(self, x):
"""
Forward pass through the layer.
Args:
x: Input tensor of shape (batch_size, input_size)
Returns:
Output tensor of shape (batch_size, output_size)
TODO: Implement matrix multiplication and bias addition
- Use self.weights for the weight matrix
- Use self.bias for the bias vector
- Return Tensor(result)
"""
### BEGIN SOLUTION
result = x.data @ self.weights
if self.use_bias:
result += self.bias
return Tensor(result)
### END SOLUTION
```
### 3. Error Handling
```python
# Include error handling in solutions
def matrix_multiply(a, b):
### BEGIN SOLUTION
if a.shape[1] != b.shape[0]:
raise ValueError(f"Cannot multiply shapes {a.shape} and {b.shape}")
result = np.dot(a.data, b.data)
return Tensor(result)
### END SOLUTION
```
## Troubleshooting
### Common Issues
1. **Marker conflicts**: Ensure nbgrader and TinyTorch markers don't interfere
2. **Cell metadata**: Check that nbgrader cell metadata is preserved
3. **Import issues**: Verify that package imports work in both environments
4. **Test failures**: Ensure hidden tests are robust and fair
### Debug Commands
```bash
# Check notebook structure
nbgrader validate assignment.ipynb
# Test auto-grading locally
nbgrader autograde --create --force assignment
# Validate student notebook
python -c "from modules.tensor.tensor_assignment import *; print('✅ Imports working')"
```
## Conclusion
The enhanced TinyTorch + nbgrader system provides:
- **Flexibility**: Support both self-learning and formal assessment
- **Scalability**: Handle large courses with automated grading
- **Quality**: Consistent, fair evaluation across all students
- **Efficiency**: Reduced instructor workload while maintaining quality
- **Integration**: Seamless with existing TinyTorch architecture
This system transforms TinyTorch from a learning framework into a complete course management solution while preserving its educational philosophy.

# Module 1: Tensor - Enhanced with nbgrader Support
This is an enhanced version of the tensor module that demonstrates dual-purpose content creation:
- **Self-learning**: Rich educational content with guided implementation
- **Auto-grading**: nbgrader-compatible assignments with hidden tests
## Dual System Benefits
1. **Single Source**: One file generates both learning and assignment materials
2. **Consistent Quality**: Same instructor solutions in both contexts
3. **Flexible Assessment**: Choose between self-paced learning or formal grading
4. **Scalable**: Handle large courses with automated feedback
## How It Works
- **TinyTorch markers**: `#| exercise_start/end` for educational content
- **nbgrader markers**: `### BEGIN/END SOLUTION` for auto-grading
- **Hidden tests**: `### BEGIN/END HIDDEN TESTS` for automatic verification
- **Dual generation**: One command creates both student notebooks and assignments

## Usage Examples
### Self-Learning Mode
Students work through the educational content step by step:
```python
# Create tensors
t1 = Tensor([1, 2, 3])
t2 = Tensor([4, 5, 6])
# Basic operations
result = t1.add(t2)
print(f"Addition: {result}")
# Matrix operations
matrix1 = Tensor([[1, 2], [3, 4]])
matrix2 = Tensor([[5, 6], [7, 8]])
product = matrix1.matmul(matrix2)
print(f"Matrix multiplication: {product}")
```
### Assignment Mode
Students submit implementations that are automatically graded:
1. **Immediate feedback**: Know if implementation is correct
2. **Partial credit**: Earn points for each working method
3. **Hidden tests**: Comprehensive coverage beyond visible examples
4. **Error handling**: Points for proper edge case handling
### Benefits of Dual System
1. **Single source**: One implementation serves both purposes
2. **Consistent quality**: Same instructor solutions everywhere
3. **Flexible assessment**: Choose the right tool for each situation
4. **Scalable**: Handle large courses with automated feedback
This approach transforms TinyTorch from a learning framework into a complete course management solution.
