## Usage
|
| 67 |
|
| 68 |
+
### Loading the Model
|
| 69 |
+
|
| 70 |
```python
|
| 71 |
from transformers import AutoModel, AutoTokenizer
|
| 72 |
+
import torch
|
| 73 |
+
|
| 74 |
+
# Load model and tokenizer
|
| 75 |
+
model = AutoModel.from_pretrained("pnny13/legion-coder-8m", trust_remote_code=True)
|
| 76 |
+
tokenizer = AutoTokenizer.from_pretrained("pnny13/legion-coder-8m", trust_remote_code=True)
|
| 77 |
|
| 78 |
+
# Set to eval mode
|
| 79 |
+
model.eval()
|
| 80 |
```
|
| 81 |
|
| 82 |
+
### Generating Code
|
| 83 |
+
|
| 84 |
+
```python
|
| 85 |
+
# Prepare prompt
|
| 86 |
+
prompt = "# Write a function to calculate factorial\ndef factorial(n):"
|
| 87 |
+
inputs = tokenizer(prompt, return_tensors="pt")
|
| 88 |
|
| 89 |
+
# Generate
|
| 90 |
+
with torch.no_grad():
|
| 91 |
+
outputs = model.generate(
|
| 92 |
+
inputs.input_ids,
|
| 93 |
+
max_length=200,
|
| 94 |
+
temperature=0.8,
|
| 95 |
+
top_p=0.95,
|
| 96 |
+
top_k=50
|
| 97 |
+
)
|
| 98 |
+
|
| 99 |
+
# Decode
|
| 100 |
+
generated_code = tokenizer.decode(outputs[0], skip_special_tokens=True)
|
| 101 |
+
print(generated_code)
|
| 102 |
+
```
|
| 103 |
+
|
| 104 |
+
## System Prompt
|
| 105 |
+
|
| 106 |
+
For optimal results, use the following system prompt:
|
| 107 |
+
|
| 108 |
+
```
|
| 109 |
+
You are Legion Coder, an expert coding assistant. Your purpose is to help users write clean, efficient, and well-documented code.
|
| 110 |
+
|
| 111 |
+
Guidelines:
|
| 112 |
+
- Write code that follows best practices and PEP 8 style guidelines
|
| 113 |
+
- Include helpful comments explaining complex logic
|
| 114 |
+
- Provide complete, runnable code examples
|
| 115 |
+
- Explain your approach before showing code when helpful
|
| 116 |
+
- If asked to debug, identify the issue and provide the corrected code
|
| 117 |
+
|
| 118 |
+
Always wrap code blocks in triple backticks with the appropriate language identifier.
|
| 119 |
+
```
|
| 120 |
+
|
| 121 |
+
## Training Details
|
| 122 |
+
|
| 123 |
+
### Training Data
|
| 124 |
+
- Python code from The Stack v2 dataset
|
| 125 |
+
- GitHub code repositories (filtered for quality)
|
| 126 |
+
- Code-specific preprocessing to handle indentation and special tokens
|
| 127 |
+
|
| 128 |
+
### Training Procedure
|
| 129 |
+
- Optimizer: AdamW
|
| 130 |
+
- Learning Rate: 5e-4 with cosine decay
|
| 131 |
+
- Batch Size: 4 with gradient accumulation
|
| 132 |
+
- Training Steps: 10,000
|
| 133 |
+
- Mixed Precision: No (CPU-optimized)
|
| 134 |
+
|
| 135 |
+
## Limitations
|
| 136 |
+
|
| 137 |
+
- **Context Length**: Limited to 1,024 tokens
|
| 138 |
+
- **Language Support**: Primarily optimized for Python
|
| 139 |
+
- **Model Size**: 44M parameters may not capture all programming patterns
|
| 140 |
+
- **Training Data**: May reflect biases present in training code
|
| 141 |
+
- **No Internet Access**: Cannot access external APIs or documentation
|
| 142 |
+
|
| 143 |
+
## Ethical Considerations
|
| 144 |
+
|
| 145 |
+
- Generated code should be reviewed before production use
|
| 146 |
+
- The model may reproduce patterns from training data; verify licensing
|
| 147 |
+
- Do not use for generating malicious code
|
| 148 |
+
- Consider environmental impact of model inference
