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.

## Quick Start AquilaChat2-7B（Chat model）
|
|||
|
|
|
|||
|
|
### 1. Inference
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
import torch
|
|||
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM
|
|||
|
|
from transformers import BitsAndBytesConfig
|
|||
|
|
|
|||
|
|
device = torch.device("cuda:0")
|
|||
|
|
model_info = "BAAI/AquilaChat2-7B"
|
|||
|
|
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 = "请给出10个要到北京旅游的理由。"
|
|||
|
|
from predict import predict
|
|||
|
|
out = predict(model, text, tokenizer=tokenizer, max_gen_len=200, top_p=0.95,
|
|||
|
|
seed=1234, topk=100, temperature=0.9, sft=True, device=device,
|
|||
|
|
model_name="AquilaChat2-7B")
|
|||
|
|
print(out)
|
|||
|
|
```
