We opensource our **Aquila2** series, now including **Aquila2**, the base language models, namely **Aquila2-7B** and **Aquila2-34B**, as well as **AquilaChat2**, the chat models, namely **AquilaChat2-7B** and **AquilaChat2-34B**, as well as the long-text chat models, namely **AquilaChat2-7B-16k** and **AquilaChat2-34B-16k** |
|
|
|
The additional details of the Aquila model will be presented in the official technical report. Please stay tuned for updates on official channels. |

|
## Updates 2024.6.6 |
|
|
|
We have updated the basic language model **Aquila2-7B**, which has the following advantages compared to the previous model: |
|
|
|
* Replaced tokenizer with higher compression ratio: |

|
| Aquila2-new | 143k | 4.60 | **4.61** | **3.78** | **3.88** | **4.22** | |
|
|
|
* The maximum processing length supported by the model has increased from 2048 to 8192 |

## Quick Start Aquila2-7B |
|
|
|
### 1. Inference |
|
Aquila2-7B is a base model that can be used for continuation. |
|
|
|
```python |
|
import torch |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
from transformers import BitsAndBytesConfig |
|
|
|
device= "cuda:0" |
|
|
|
# Model Name |
|
model_name = 'BAAI/Aquila2-7B' |
|
|
|
# load model and tokenizer |
|
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_name, torch_dtype=torch.bfloat16, trust_remote_code=True, |
|
# quantization_config=quantization_config # Uncomment this one for 4-bit quantization |
|
) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(path, trust_remote_code=True) |
|
|
|
model.eval() |
|
|
|
model.to(device) |
|
|
|
# Example |
|
text = "The meaning of life is" |
|
tokens = tokenizer.encode_plus(text)['input_ids'] |
|
tokens = torch.tensor(tokens)[None,].to(device) |
|
|
|
with torch.no_grad(): |
|
out = model.generate(tokens, do_sample=False, max_length=128, eos_token_id=tokenizer.eos_token_id)[0] |
|
out = tokenizer.decode(out.cpu().numpy().tolist()) |
|
print(out) |
|
``` |
