How to use pruned models |
|
```python |
|
import torch |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
base_model = 'llama-2-7b' |
|
comp_method = 'magnitude_unstructured' |
|
comp_degree = 0.2 |
|
model_path = f'vita-group/{base_model}_{comp_method}' |
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_path, |
|
revision=f's{comp_degree}', |
|
torch_dtype=torch.float16, |
|
low_cpu_mem_usage=True, |
|
device_map="auto" |
|
) |
|
tokenizer = AutoTokenizer.from_pretrained('meta-llama/Llama-2-7b-hf') |
|
input_ids = tokenizer('Hello! I am a VITA-compressed-LLM chatbot!', return_tensors='pt').input_ids.cuda() |
|
outputs = model.generate(input_ids, max_new_tokens=128) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |

|
How to use quantized models |
|
```python |
|
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig |
|
model_path = 'vita-group/llama-2-7b_wanda_2_4_gptq_4bit_128g' |
|
model = AutoGPTQForCausalLM.from_quantized( |
|
model_path, |
|
# inject_fused_attention=False, # or |
|
disable_exllama=True, |
|
device_map='auto', |
|
) |
|
``` |
