## Usage
|
| 45 |
+
|
| 46 |
+
### Quick Inference
|
| 47 |
+
|
| 48 |
+
```python
|
| 49 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 50 |
+
|
| 51 |
+
model = AutoModelForCausalLM.from_pretrained(
|
| 52 |
+
"Irfanuruchi/phi-2-chat",
|
| 53 |
+
trust_remote_code=True,
|
| 54 |
+
device_map="auto"
|
| 55 |
+
)
|
| 56 |
+
tokenizer = AutoTokenizer.from_pretrained("Irfanuruchi/phi-2-chat")
|
| 57 |
+
|
| 58 |
+
# Recommended prompt format:
|
| 59 |
+
input_text = "<|user|>Explain dark matter<|assistant|>"
|
| 60 |
+
inputs = tokenizer(input_text, return_tensors="pt").to("cuda")
|
| 61 |
+
outputs = model.generate(**inputs, max_new_tokens=200)
|
| 62 |
+
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
|
| 63 |
+
|
| 64 |
+
```
