This Qwen 3 4B model was fine-tuned on the Hermes 3 dataset to enhance its general chatting capabilities while retaining Qwen's Reasoning capabilities.
|
||||
|
||||
## transformers
|
||||
As the qwen team suggested to use
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||||
|
||||
model_name = "ertghiu256/Qwen3-Hermes-4b"
|
||||
|
||||
# load the tokenizer and the model
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
||||
model = AutoModelForCausalLM.from_pretrained(
|
||||
model_name,
|
||||
torch_dtype="auto",
|
||||
device_map="auto"
|
||||
)
|
||||
|
||||
# prepare the model input
|
||||
prompt = "Give me a short introduction to large language model."
|
||||
messages = [
|
||||
{"role": "user", "content": prompt}
|
||||
]
|
||||
text = tokenizer.apply_chat_template(
|
||||
messages,
|
||||
tokenize=False,
|
||||
add_generation_prompt=True,
|
||||
enable_thinking=True # Switches between thinking and non-thinking modes. Default is True.
|
||||
)
|
||||
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
|
||||
|
||||
# conduct text completion
|
||||
generated_ids = model.generate(
|
||||
**model_inputs,
|
||||
max_new_tokens=32768
|
||||
)
|
||||
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist()
|
||||
|
||||
# parsing thinking content
|
||||
try:
|
||||
# rindex finding 151668 (</think>)
|
||||
index = len(output_ids) - output_ids[::-1].index(151668)
|
||||
except ValueError:
|
||||
index = 0
|
||||
|
||||
thinking_content = tokenizer.decode(output_ids[:index], skip_special_tokens=True).strip("\n")
|
||||
content = tokenizer.decode(output_ids[index:], skip_special_tokens=True).strip("\n")
|
||||
|
||||
print("thinking content:", thinking_content)
|
||||
print("content:", content)
