|
The additional details of the Aquila model will be presented in the official technical report. Please stay tuned for updates on official channels. |

## Quick Start Aquila2-7B |
|
|
|
### 1. Inference |
|
Aquila2-7B is a base model that can be used for continuation. |
|
|
|
```python |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
from transformers import BitsAndBytesConfig |
|
|
|
device = torch.device("cuda") |
|
model_info = "BAAI/Aquila2-7B" |
|
tokenizer = AutoTokenizer.from_pretrained(model_info, trust_remote_code=True) |
|
quantization_config=BitsAndBytesConfig( |
|
load_in_4bit=True, |
|
bnb_4bit_use_double_quant=True, |
|
bnb_4bit_quant_type="nf4", |
|
bnb_4bit_compute_dtype=torch.bfloat16, |
|
) |
|
model = AutoModelForCausalLM.from_pretrained(model_info, trust_remote_code=True, torch_dtype=torch.float16, |
|
# quantization_config=quantization_config, # Uncomment this line for 4bit quantization |
|
) |
|
model.eval() |
|
model.to(device) |
|
text = "杭州亚运会的亮点和期待 2023年9月23日至10月8日，杭州将举办第19届亚洲运动会" |
|
tokens = tokenizer.encode_plus(text)['input_ids'] |
|
tokens = torch.tensor(tokens)[None,].to(device) |
|
stop_tokens = ["###", "[UNK]", "</s>"] |
|
with torch.no_grad(): |
|
out = model.generate(tokens, do_sample=True, max_length=512, eos_token_id=100007, bad_words_ids=[[tokenizer.encode(token)[0] for token in stop_tokens]])[0] |
|
out = tokenizer.decode(out.cpu().numpy().tolist()) |
|
print(out) |
|
``` |
