## π§ Example Usage (with repetition control)
|
| 69 |
+
|
| 70 |
+
```python
|
| 71 |
+
from transformers import AutoTokenizer, AutoModelForCausalLM
|
| 72 |
+
|
| 73 |
+
model_id = "yasserrmd/RSCaLM-138M-LLaMA"
|
| 74 |
+
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
| 75 |
+
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")
|
| 76 |
+
|
| 77 |
+
prompt = "when a man goes to fishing"
|
| 78 |
+
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
|
| 79 |
+
|
| 80 |
+
# Generation settings to reduce repetition
|
| 81 |
+
outputs = model.generate(
|
| 82 |
+
**inputs,
|
| 83 |
+
max_new_tokens=100, # Limit length of output
|
| 84 |
+
temperature=0.7, # Lower temperature = more focused
|
| 85 |
+
top_p=0.9, # Nucleus sampling
|
| 86 |
+
top_k=50, # Top-K filtering
|
| 87 |
+
repetition_penalty=1.2, # Penalize repeating tokens
|
| 88 |

### π‘ Tips for controlling repetition:
|
| 98 |
+
|
| 99 |
+
1. **`repetition_penalty`** β Increase slightly above `1.0` (e.g., `1.2β1.5`) to discourage repeated phrases.
|
| 100 |
+
2. **`no_repeat_ngram_size`** β Set to `3` or `4` to avoid repeated n-grams.
|
| 101 |
+
3. **`top_k` + `top_p`** β Combine both for better randomness control.
|
| 102 |
+
4. **Lower `temperature`** β Keeps outputs focused and less chaotic.
|
| 103 |
+
5. **Stop sequences** β Add specific words/phrases to halt generation early if needed.
